Newly designed cylinder head, new cam profile249 cm 3 Liquid - cooled, DOHC 4 - valve Engine with New Cylinder HeadNew cylinder head realizes a new air flow that further improves the effect of down draft. By optimizing the intake port shape which becomes more straight intake for the 2016 model and the layout of the collecting part of the exhaust port, it is possible to improve the intake / exhaust efficiency and increase the intake flow rate. The intake and exhaust cam profile is also optimized, both the intake and exhaust cams are increased in the maximum lift amount, the reinforced valve spring is incorporated and the valve seat diameter is expanded. Together with these effects, it combines excellent low and medium speed performance with pulling power & power feeling that is outstanding at medium and high speeds.

Yamaha is in the position of offering two completely different 250cc off-road bikes for the same purpose. YZ250FX TECH INSPECTIONIn 2015 Yamaha created the 250FX from the then-current YZ250F motocross bike. To make it into an off-road bike, Yamaha engineers concentrated on things that owners couldn’t do on their own. It was no quieter than the motocross bike, and it did not have a spark arrestor. But, the bike seems a little more dated because of the release of an all-new 2019 YZ250F motocross bike.
