Yamaha R1 inspired TZ750 by Mule Motorcycles

Yamaha R1 inspired TZ750 by Mule Motorcycles with the contribution of Wayne Rainey

Former rider Wayne Rainey, despite the serious accident in '93 witch made ​​him paralyzed, he never moved away from the world of motorcycles and racing. With some frends established MotoAmerica , a championship road racing that is part of the AMA circuit.

Their names are Terry Karges, Chuck Aksland and Richard Varner. The latter is the man behind this bike, and who contacted Richard Pollock, of Mule Motorcycles, workshop based in Poway, California town in the county of San Diego.

A look at some of his bikes seem to prefer the style tracker, but this time the request was different. The bike used is in fact a 2004 R1's team of Larry Pegram and has been designed taking inspiration from the TZ750, motorcycles produced between 1974 and 1979 for the races of Formula 750, a kind of forerunner of the Superbike.

The frame is entirely handmade, made ​​of chrome molybdenum 4130, with rear frame built using rod ends, while the swingarm is in 6061, made ​​by Trac Dynamics. The fairing is that the TZ750, recovered and obviously adapted. Made from scratch are aluminum tank and air box. One of the biggest challenges of the bike was packaging all the electronics and figuring out the wiring,  The ECU now lives under the fairing, à la TZ750, in a sweet, welded bracket on the fairing mount, and a wiring block is mounted between frame spars on the left. A lightweight carbon-fiber-shell lithium-ion battery from Lithionics is mounted in the tailsection.

The 18-inch wheels are the same used at the rear of the Harley-Davidson XLCR . We hope that just have not been cannibalized two bikes but whether it's new old stock parts. Both channels of the circles have been widened by the specialist Kosman up to 2.75 inches in front and 4.5 behind, while Mule Motorcycles took care to realize all the components to fit brakes, hubs and crown of the original R1.

The bike uses the best of cycling, including Öhlins suspension and Brembo brake calipers. The Italian company has provided the radial calipers, while discs were made ​​by Ultra Lite Brakes with noble materials such as titanium coated ceramic. A disc coast beauty of $ 1,000 and is lighter by 30% compared to steel.

Now the R1 is lighter than a Superbike, develops 180 hp at the wheel and is ready to mount some lights.
