Brands Superbike Unlimited
Product Code: SBU-YZFR1
Availability: In Stock

We are offering for purchase one of our most closely-watched projects, our National Championship-winning Yamaha YZF-R1 superbike. The ultimate race or track day Yamaha YZF-R1, ultra light, ultra fast and perfectly dialed in.

This bike has had an absolutely tremendous amount of development in every aspect and features impossible-to-get parts and a chassis, suspension, engine and electronics setup that is proven to win professional Superbike races and qualify on Pole position. With a dry weight under 360lbs and a power output of 45 more horsepower than a stock YZF-R1 (and making 6 more horsepower than our former factory BSB bike), this motorcycle is sure to exceed the performance expectations of any rider. 

The engine was built from a completely new base & has only dyno break in time and a couple of on-track sessions to fully break it in. We have the original engine in Superstock spec available as well.

The chassis is fully refreshed, with new bearings all around. 

We will set the bike up for the purchaser and it will include a setup session of the electronics, chassis and suspension as needed trackside by Tyler & Freddy.
