Jon Towle, the official, sanctioned, Bikernet, new-model rider reporter turned in a road test recently, and I spotted this Sportster in the background. The editorial board directive was unanimous--we need a feature quick. As it turned out this racy machine was built by one of Jon's Huntington Beach, California neighbors. Jon was able to dodge the high-tech writing assignment by asking the owner Kevin Blaty to document the build. Here goes:

I have always wanted to build a street legal version of the '70s H-D XRTT factory road racer ridden by the famous H.D. wreaking crew. I was just a rug rat at the time, but I kept the dream alive until I could afford a new 2001 stock XL 883. I purchased the bike new from Laidlaws H-D and rode it stock until break-in was complete. Then I began tearing it down.

The first thing I modified were the wheels. I scraped the 19 front and 16-inch rear in favor of 18 front and rear. I used Exel shouldered alloy rims with Buchannan stainless steel spokes. I moved the fork tubes up 5/8-inch in the triple clamps, and installed Works Performance shocks ¾-inch longer than stock for improved cornering, with a J&P Cycles steering dampener. I also added floating disk rotors.

Next, I fabricated a pair of rear sets from 6061-T6 aluminum alloy moved back 10 inches from the stock position. I installed a Supertrapp exhaust system and a Pro-Flo 39mm clip-on handle bars with old "Hap Jones" 3-inch billet mirrors. I also modified the switch gear to reroute the wire bundles and used 1-inch alloy sleeves over the 7/8-inch bars.

I purchased the '70s XRTT fiberglass gas tank, seat and fairing from Air-Tech in San Marcos, California. I had to modify the tank by moving the petcock threaded inserts as they inter- feared with the forward valve cover. I fabricated special brackets to install the tank. To secure the tank, I used a 1-inch wide stainless steal strap with an older FL battery strap (like the old days).

I removed the front fender and installed a BCS Enterprises fork brace from a Yamaha MX 360. I cut the rear fender and fender struts to install the seat to match the XRTT paint scheme, then took it to Perry's Auto body in Westminster, California for the final clear coat.

The stock 883 cylinders were bored out to 1200cc. Each cylinder weighed 10lbs. After boring, they weighed in at only 5lbs each. The engine work was handled by American Rider Cycle Supply in Huntington Beach, California. I used Buell Thunderstorm heads, and J&E 10.5- to-1 high compression pistons both purchased on E-Bay.

I also installed was a Balance Masters clutch mount engine balancer and a Jagg oil cooler. I retained the stock cams for street use. Then I installed a Yost Power Tube in the stock CV carb with a Doherty Air Cleaner assembly for improved breathing. I made a custom bracket to install a Nology Ignition Coil. I moved the ignition switch to the left side with a custom bracket to mount it next to the choke lever and finished with Nology Hot Wires. The headlight was moved down 3 inches from stock, turned upside down and mounted to the lower triple clamp with a custom made bracket.

I removed the front end to modify the steering stops for clearance between the handle bars and the fuel tank. I also mounted a custom made bracket to the steering head for the front fairing mount. In order to gain clearance for the long- circuit fairing.

I removed the stock kickstand and made a bracket to install a '06 Triumph Daytona alloy kickstand on the swing arm using the passenger peg threaded mount. Still to come, I will modify the fairing to mount the head light in a solid position, mount the mirrors to the fairing, fabricate the fairing mounts, paint the fairing with the XRTT paint scheme, mount the windshield and then I'm done!

Well, it's never really done, now is it.
