The 2017 model embodies the concept of "inheriting The Ultimate YZ 'DNA".New specification engine which evolved by pursuit of thorough new air flow etc. is installed in the same frame as 2016 YZ450F.The driving potential backed up by the original "front air intake / rear exhaust / backward inclination cylinder" design has also evolved.The graphic also evolved to "Team Yamaha" Cool "Blue", rear fender's logo is a message of support from "Off-road Mania".Respond to the passion for "Win". Newly designed cylinder head, new cam profile 249 cm 3 Liquid-cooled, DOHC 4-valve Engine with New Cylinder Head The new cylinder head realizes a new air flow that further improves the downdraft effect.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.YZ potential has evolved again.
