O.S. Engines is pleased to present the all-new O.S. SPEED R21 SHIMO EDITION 3.
The latest collaboration with O.S. team driver Takaaki Shimo.
- In the exhaust section of the crankcase, thanks to the use of the spacers provided, the engine offers more linear performance from low to high revs.
- The liner now has 9 transfers and the piston has been given a new treatment to extend the life of the engine.
- The carburetor uses a “dust ring” to improve and stabilize idle speed, preventing fuel leaks and air in the line.
- New dark gold cylinder head redesigned for better cooling and a matching venturi to create a brand new look.
- To maximize performance, the combo kit comes with a TR03 EFRA2196 resonator + MR05 elbow.
