Update 3: Wicked Little 2-Stroke Yamaha Tracker-Bobber
Moving this to the top for a bit since so many folks had questions about it.
Update 3: Found the build thread! An alert reader over on ADV rider found the build thread on this bike. A lot of folks have been asking for more info so here you go!
http://www.dotheton.com/forum/index.php?topic=12857.0
From the comments (Thanks SakeRacer). More info Here: http://www.pipeburn.com/home/2010/9/9/1973-yamaha-rd250-street-tracker.html
Sorry to Pipeburn. I didn't realize it originated on their site. TONS of great stuff over there so check them out often.
My observant commentors make some good points about the classification of this bike. Tracker of Bobber? I see a lot of elements of both styles here and to be honest I'm not crazy about pigeon holing bikes all that much so lets call it a tracker-bobber. Whatever you call it it's still freaking cool!
That's got backroad fun written all over it.

Reader Submittal. Custom built Indian "Chout"
Buck Pinkerton sends in this really cool old Indian! I would love to own something like this. Damm near one of a kind! Thanks!
Hi,
This is a friend's Indian Chout. It was built by her father before she was born, ostensibly a 1929 Scout frame holding a 1940 Bonneville Chief engine that he just happened to find in a crate at the southwest airbase where he was stationed. The forks look to be latter day chief. Some time in the 1980s the bike passed through the hands of a "restorer" who added the H-D front fender and odd looking instrument pod. At least he painted it right and stayed out of the engine. The bike is back in the family now, and from stories I've been told it was one fast machine.
Ride safe,
Buck Pilkenton

Reader Ride. Sweet Parilla 250 Work In Progress.
Danilo writes in:
Love your site. Thought you'd get a kick out of my Parilla 250 project. Purchased it in Minneapolis last month, hadn't run in years. Cleaned up the points, new battery and swapped out the VHB Dellorto for the original SS1 with remote bowl that came in the parts box, gave it a couple of kicks and... Nothing. Took it out in the alley and it bump-started on the third try.
Put 50 miles on it this weekend, including a stop at Acetoberfest in Chicago. Still bumping it, but as soon as I get new points and condenser that'll be a thing of the past. When winter hits the frame goes out for checking/bracing, and then I'm going to give it the cosmetic treatment.
That's a heck of a find! Perfect starting point! Thank for the Pics!
What beautiful engine!

This is one of Ron Woods' projects. Matt Weidman tried to make the mile at Arizona back on 5/1 with this but missed the field. He's supposed to run it again on Saturday 10/9 and try to get it in the National again after Ron got the bugs worked out of it.
Very sweet looking machine! With the rules being 'opened up' in AMA Flat Track this year it has made for some very interesting combinations, as 12 different manufacturers and their respective models are available to race in the Grand National Expert Twins Class. Earlier this year not only did a Ducati 1098 win--at Arizona with Joe Kopp--but Bill Werner, Jay Springsteen and Bryan Smith took a Kawasaki 650 Ninja-based parallel twin to the win here at Indy and at Springfield. Jeremy Higgins put a KTM in the main at Minnesota a couple of weeks ago, and Triumph put together a nice package based on the 865 Bonneville and has made four mains this year.
Very cool stuff, and as always Steve, you have kept things on the cutting edge here man! Keep up the great work!
Awesome! Thanks for that!
I think I posted something on this bike a long while back but I'm not positive. Really excellent build. Your eyes are not playing tricks. The front shock mount is in fact on the rear of the cylinder. Bold stuff.

HONDA CBR1000RR 2010
Honda UK has unveiled today two CBR1000RR Fireblades Special Editions - one ‘Hutchy’ and one ‘McGuinness’ – to commemorate the achievements of these two legendary TT road racers. Both bikes feature awesome special-edition paintwork celebrating Honda’s amazingly successful Isle of Man TT campaigns with two record-breaking riders: Ian Hutchinson and John McGuinness.
Ian Hutchinson tore-up the record books at this year’s TT races with an unprecedented five out of five solo wins in the Superbike, Superstock, Senior and two Supersport races. To mark his success on his Padgetts Honda race bikes, the ‘Hutchy’ CBR1000RR celebrates that amazing feat with a brilliant pearlescent white paint scheme that features a map of the 37.73-mile Isle of Man TT course, outlined around the top of the bike. A red line faithfully follows the twists and turns of the historic mountain course, complete with corner names. Both side fairings of the Fireblade are emblazoned with a commemorative decal illustrating all five of Hutchinson’s victories at this year’s TT races and, his overall TT Championship victory. There is also Ian’s unique ‘Hutchy’ graphic on the tank, along with his signature.
The John McGuinness special-edition makes an ingenious play on the fastest man around the TT course’s name. John has traditionally used a representation of a pint of the black stuff on the back of his leathers, and the ‘McGuinness’ CBR1000RR takes this a stage further by turning the Fireblade into a two-wheeled pint of it! A beautiful and intricate paint-scheme replicates the look of a pint, complete with dew-drops of condensation on the fairings and the creamy white head that only the perfectly poured pint has. John’s bike is also adorned on the fairings with a gold map of the TT course and his lap record of 131.578mph and, each bike is also autographed by John, enhancing its exclusivity even further.
Both riders are made up that their Island exploits are being celebrated in such a way. Hutchy said: “It’s exciting and really nice of Honda to make these Special Edition bikes. Better still, I’ve been given the first one which is such a lovely gesture. It’s an awesome bike to ride the Fireblade – how we did in the Superstock race shows how good it is. I won’t be riding mine though: it will be going straight in the living room! On the paintwork, the skill and attention to detail is just stunning. When you go up close, you can see just how pearlescent the white paint is, it’s an amazing piece of work.”
McGuinness remarked: “I’m so proud to have a Special Edition bike like this. I’m honoured that Honda has recognised my achievements at the TT in this way and it cheers me up after a 2010 Isle of Man campaign that was hit by bad luck. I feel part of the Fireblade programme now with my wins on the current ‘Blade and previous versions, so it’s very special to know people can buy this bike. With the one that Honda has given me, like Hutchy, I’m not going to use it, it will join my collection. I’ve got an older style ‘Blade, a V-twin SP-1 and a number of other Hondas. I’m always going to keep hold of it. The paintwork is amazing and every owner’s bike will be unique, as each of the bubbles on the bodywork is done by hand and different every time. It’s a work of art.”
Both bikes are available now to order, from Honda motorcycle dealerships across the country, in both standard and ABS-equipped versions. The ‘Hutchy’ or ‘McGuinness’ Special Edition ‘Blades are just £1,000 above current Fireblade on-the-road prices, meaning these truly memorable editions are priced at £11,725 OTR, or £12,375 OTR with the added comfort of Honda’s amazing electronically-controlled C-ABS braking system developed specifically for sports bikes. Both machines are also available with Honda’s current great 0% APR and 2/9% APR finance offers which end on 30 September 2010.

Engine/Drivetrain
- Liquid-cooled DOHC 16-valve 998cc four-stroke inline four-cylinder engine features bore-and-stroke dimensions of 75mm x 56.5mm.
- Sixteen-valve cylinder head features 29mm intake and 24mm exhaust valves with a 12.2:1 compression ratio for efficient combustion and high horsepower.
- Intake valve features double-spring design for optimum performance at high rpm.
- Direct shim-under-bucket valve actuation system ensures high-rpm durability and allows 16,000-mile valve maintenance intervals.
- Lightweight nutless connecting rods.
- Iridium-tip spark plugs improve fuel combustion and performance.
- DSFI system features two injectors per cylinder--one upper and one lower--controlled by an electronic control unit (ECU) that senses rpm and throttle opening. Lower injector enhances rideability while upper injector improves top-end horsepower. At lower rpm only the lower injector is working. At higher rpm, both injectors are activated. The system uses 44mm throttle bodies.
- Denso injectors with lightweight valving for faster reaction time and 12 holes per injector improve atomization of fuel mixture for optimum combustion efficiency and power.
- Auto-enriching system is integrated into programmed fuel injection (PGM-FI) module, eliminating the need for a manual choke.
- Forged aluminum pistons with moly surface treatment for reduced friction.
- Aluminum composite cylinder sleeves are high-pressure-formed from sintered aluminum powder impregnated with ceramic and graphite. The lightweight composite sleeves provide better wear resistance and superior heat dissipation compared to conventional sleeves.
- ECU provides two digital 3-D fuel-injection maps for each cylinder and two digital 3-D ignition maps for cylinder pairs, creating ideal fuel mixture and spark advance settings for superb rideability.
- Ram-air system allows high volume of cool air to the 8.35-liter airbox for linear power delivery and incredible engine performance.
- Stainless steel four-into-two-into-one center-up exhaust with twin outlets and titanium core increases lean angle and reduces wind drag.

Chassis/Suspension
- Lightweight, twin-spar aluminum frame utilizes RC211V technology.
- Aluminum-hybrid rear swingarm is longest in class for superior traction under hard acceleration.
- New aluminum subframe is lightweight and easily removed for ease of maintenance.
- HESD is a rotary-type steering damper that electronically modulates steering damping based on road speed and acceleration. An ECU senses road speed and acceleration and then sends a signal to a solenoid. The solenoid controls an oil-pressure relief valve within the damper unit. At slower speeds the relief valve is open, allowing for a free flow of oil through the damper unit, resulting in reduced damping force and lighter steering effort. At higher speeds the flow of oil is restricted, resulting in increased damping force and additional stability. HESD is the first steering-damping system that makes it possible to increase high-speed performance while maintaining low-speed handling.
- 43mm inverted aluminum-slider Honda Multi-Action System (HMAS) cartridge front fork features spring preload and rebound and compression damping adjustability, and offers precise action and unparalleled rigidity.
- Unit Pro-Link rear suspension system is patterned after the RC211V MotoGP machine. In this system, the upper shock mount is contained within the swingarm rather than the frame. With no top frame mount for the shock, this unique system reduces negative suspension energy from being transmitted into the frame, allowing optimum frame rigidity and improved rideability out of corners. The HMAS shock offers rebound and compression damping and spring preload adjustability.
- Front-brake system features radial-mounted four-piston calipers and 320mm floating discs, and a 220mm rear disc with a single-piston caliper for exceptional stopping power.
- Super-light, aluminum-alloy hollow-spoke wheels feature race-spec 3.5 x 17-inch front and 6.0 x 17-inch rear dimensions.

XR1200X HARLEY-DAVIDSON
As hard as it may be to believe, Harley-Davidson’s XR1200X model was only available in Europe ever since it was introduced a year ago, keeping Americans away from the bike’s 74 pound-feet of torque at 4000 rpm and 40-degree lean angle, not to mention the impressive looks. But it is all over now that Harley announced that the 2011 model year comes stateside (how does that even sound considering the American company’s huge fan clubs stretching from coast to coast).
For a price of $11,799, the 2011 Harley-Davidson XR1200X offers a lot. To begin with, the sports bike features Showa Big Piston front forks with adjustable rebound, compression and preload working together with the dual Showa rear shocks with 36mm pistons and piggyback nitrogen-charged reservoirs. Also, the front brakes – 292mm full-floating rotors and four-piston calipers – are supplied by Nissin.
But this bike is definitely all about the looks and with the rider positioned in a rather sporty riding position – at 29.2 inches from the ground, gripping on rear-mount pegs and holding on to dirt track-style handlebars – it will most likely be a hit in the States as well. So the question remains: why would H-D test the old continent market before introducing the bike here? Anyway, colors available for 2011 are Black Denim and White Hot Denim.
Press Release
XR1200X™ TAKES SPORTSTER® PERFORMANCE TO A NEW LEVEL
Fully-Adjustable Premium Suspension and Full-Floating Front Brake Rotors
The XR1200X is Harley-Davidson® Sportster performance honed to its finest edge. Introduced in 2010 for export markets only, the XR1200X will be available through Harley-Davidson dealers in the United States as a 2011 model. Equipped with fully-adjustable Showa® front and rear suspension components, the 2011 XR1200X can be dialed in to match rider weight, riding style and road conditions. The XR1200X combines this premium suspension with enhanced front brakes and the responsive punch of a high-compression, 1200cc Evolution® V-Twin engine in a dynamic, street-performance motorcycle.
With a tank and tail section designed to evoke the legendary Harley-Davidson XR750 – the king of the gritty American flat-track scene – the XR1200X puts its mechanical character on display. Wide flat-track bars and rearset footpegs position an assertive rider for active control. The XR1200X has a blacked-out powertrain and exhaust, revised tank graphics, and black wheels with an orange rim pinstripe. The XR1200X will be offered in two colors: Black Denim and White Hot Denim.
Key XR1200X Features
= Showa Big Piston Front fork (BPF) eliminates many of the internal components used in a cartridge-type fork, resulting in lighter overall fork weight. The large-diameter of the BPF internal piston allows a reduction in damping pressure for outstanding feedback and smooth action. Rebound and compression damping may be fine tuned with adjuster screws located on top of the fork bolts. The spring pre-load is adjusted with a M5 hex screw on the axle holders.
= Showa rear shocks feature 36mm pistons with piggy-back nitrogen charged reservoirs. The compression damping may be adjusted with a knob on top of the reservoir. Rebound is adjusted with a thumb wheel on the lower clevis. Rear spring pre-load is also adjustable.
= Nissin® dual front brakes feature 292mm full-floating rotors and four-piston calipers.
= Isolation-mounted XL Evolution 1200 cc V-Twin engine with black powdercoat finish features downdraft Electronic Sequential Port Fuel Injection (ESPFI), high-performance camshafts, precision oil-cooled cylinder heads and a large-capacity oil cooler. Compression ratio is 10:1. The engine is rated at 74 ft. lbs. peak torque @ 4000 rpm (per SAE J1349).
= Upswept, high-volume 2-1-2 straight-shot exhaust system with satin black finish offers extra cornering clearance.
= Chassis features a high-performance designed tubular mild steel frame. The rigid, cast-aluminum swingarm is engineered to enhance handling.
= Dunlop® Qualifier D209 tires were designed specifically for the XR1200X.
= Three-spoke lightweight cast-aluminum wheels, 18-inch front / 17-inch rear, are finished in gloss black with an orange pinstripe on the rim.
= Wide, black dirt-track handlebar for enhanced steering leverage and comfort.
= Rearset foot pegs for additional cornering clearance.
= Compact instrument display with white-faced analog tachometer, digital speedometer, dual trip meter and clock.
= 3.5-gallon fuel tank with aircraft-style aluminum alloy fuel filler.
= 29.2-inch seat height with standard passenger pillion and foot pegs.
= Optional Harley-Davidson® Smart Security System.
