Scorpa SY-250F Racing
|
|
|
The trials bike which lovers of Yamaha four-stroke technology and Scorpa's trials design philosphy have been waiting for, the SY-250F Racing combines a modified-for-trials titanium five-valve Yamaha WR250F motor with a twin-spar chrome-moly frame designed to keep the motor mass centralized and as low as possible. This frame also maximizes the four-stroke motor's power characteristics to allow it to put down solid traction while still allowing the bike to remain nimble and attack vertical obstacles.
This top-of-the-line machine includes all of the the highest quality parts we have come to expect from Scorpa, including billet aluminum triple clamps and footpegs, tapered bars, latest-generation Marzocchi black-nitride coated forks, Sach rear-shock, and an innovative exhaust system using a muffler mounted directly below the airbox, improving mass centralization and maximizing airflow to the carburetor.
