It has one of the best suspensions that even a person of 180-pound weight can easily ride on.
Brakes
This bike has a super-power engine, and to slow it down, Yamaha needs a powerful braking system, so Yamaha added a 270 mm Hydraulic disc on the front, and for the rear side, it has a 240mm Hydraulic disc. These are more rigid than ever and have a finer feel at the lever. The brake pad was improved and had higher friction material for good braking. Yamaha also upgraded its clipper position by increasing its size. They collectively work to give its rider a good and safer ride.
Dimensions
One of the most important things you should consider while choosing a bike is its dimensions. Does the bike you choose have a suitable dimension for your body, or should you consider something else if it’s not fulfilling your requirements?

You will get a decent 13.2 inches of ground clearance and 58.1 inches wheelbase that will provide an extra comfortable ride. You will get a good leg position due to the 26.8-degree rake. Furthermore, it has 4.7 inches trail size.
Fuel System

The fuel tank can store up to 1.6 gals of fuel in it. One of the loopholes of his bike is that it has a plastic fuel tank which causes the fuel to evaporate early.
Tires
The tires are the only part of a bike in contact with the ground. A right tire has a good grip on the ground, preventing the bike from skidding. Yamaha wants to improve its tire quality, so it moved from Bridgestone to Dunlop in 2022.
This bike has 80/100-21 Dunlop® Geomax MX33F front tire and 110/90-19 Dunlop® Geomax MX33 inches rear tire. These tires have a three-cross-spoke pattern that improves traction and stability by absorbing the bumps.
