Yamaha has refined its distinct rearward-slanted cylinder design for the 2018 YZ450F engine – complete with a rear exhaust and forward-mounted downdraft intake system.
The all-new cylinder head is lighter and the cylinder slant is more upright to work with the bike’s updated frame for optimised front weight distribution.
