What makes a Yamaha YZ450F a good bike?
Slowing the YZ450F down below 9000 rpm fixed the Yamaha’s bad reputation as a bike that didn’t like to hold a line at turn-in. Less power translated into more control, especially at the front tire, and the end result of the unique two-part powerband was better handling. Plus, what it lacked below 9000 rpm, it made up for above it.
Why are the valves lighter on a Yamaha YZ450F?
The new valves were more than forty percent lighter than the previous valves, allowing for lighter and softer valve springs, in turn allowing a quicker revving engine, improved throttle response, higher rev ceilings, and more power.

Why is my YZ450F not starting at all?
Bought a new 2019 YZ450F 6 weeks ago, after 8 hours it wouldn’t start, checked the inlets valves and they were totally tight so took it into my local dealers for setting. Loads of sand in the inlet manifold and throttle body so I put it down to my bad maintenance and over enthusiastic use of the power wash.
What was the original weight of the Yamaha YZ450F?
Next, the frame and plastic were updated for a new, sleeker look. Additionally, the YZF’s weight was decreased from its original 250 lb (110 kg) to 233 lb (106 kg). The bike made tremendous power; however, many thought that the bike had too much power for a motocross track.

Is the Yamaha YZ450F FX compatible with smart phones?
Yamaha now offers their power tuner app for any smart phone, which gives you the ability to load pre-set maps into the bike as well as giving you the ability to tailor your own maps. One thing that I am often asked is if the YZ450F maps will work in the FX and sadly the answer is “no”.
