"My SRX was purchased new in the spring of 1986 at Fremont Yamaha by my old boss, Mike Sorge. He was instrumental in getting me into all the different aspects of motorcycling and into developing all the parts of the bike, from the engine to the paint scheme. It started out with black bodywork on the stock gray frame, then purple ghost flames on a baby blue powder-coated frame and wheels. One day Mike saw a Buell S3 in silver with a bluish-purple translucent frame and that was that. It's the latest scheme and, in my opinion, the best.

"The single-cylinder engine evolved from a simple slip-on exhaust with minor jetting changes to the fully developed ripper it is today. I've got dyno charts showing 69 horsepower at the rear wheel! We re-sleeved the cylinder to hold a 621cc big-bore Aris forged piston, ported the head, installed stronger valve springs with titanium retainers, a White Brothers roadrace cam, Barnett clutch assembly, 31mm Keihin smoothbore carbs and a custom stainless reverse-cone exhaust. In this configuration, the SRX ran the quarter-mile in 12.28 seconds at 112 mph despite not being able to fully open the throttle in first gear; I suspect it could have run even harder had the chassis been properly set up for drag racing. It was also roadraced several times and used as a daily commuter. It has proven to be absolutely bombproof through nearly 24 years of hard use.

"The chassis currently incorporates a complete Yamaha YZF-R1 front end with a Ducati Monster fender. It was a major pain in the butt to change, but worth it! It also features an Öhlins steering damper and twin Öhlins piggyback shocks bolted to a Yamaha FZR400 aluminum swingarm with an FZR600 rear wheel and R1 brake. Steel-braided brake lines are fitted front and rear. Handmade billet components include the rearsets, motor mounts, sprocket cover, chain guard, exhaust hangers and miscellaneous other bits and pieces. The handlebars are motocross-style Pro Tapers using a Honda CRF450R clutch lever/compression release. An Acerbis headlight is topped with a custom tachometer, the stock warning-lamp array and LED lights all around. We finished it with a Corbin seat, which took a few times to get right. It has to be the most fun bike I've ever owned!"
