CYLINDER WORKS offers this replacement cylinder for your YAMAHA YZF 450cc and YAMAHA WRF 450cc motocrosser. This cylinder has exactly the same characteristics as the original. The diagrams, however, have been slightly enlarged to increase performance at high revs, without neglecting torque. The quality is excellent, as is the finish. The nyckasil is of good quality, as is the aluminum used for this top-end engine, guaranteeing reliability and performance. It's an excellent alternative for refurbishing your motor. We strongly advise you to take with this cylinder a VERTEX piston for increased reliability.
