Best for
It's built as a supermotard, designed for flickable handling on tight, twisty tarmac and light urban duties rather than long-distance cruising or serious off-road work.
Built for
Expect a raw, agile, single-cylinder character with strong torque feel low down, sharp steering, and a top speed that reflects its motard focus rather than outright speed.
Not ideal for
This is not the right bike for riders seeking high-speed touring comfort, pillion-friendly ergonomics, or serious long-distance highway cruising.

Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.

At 830mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with balls of both feet on the 2000 MuZ Mastiff, with a cramped knee angle of around 70 degrees and a slightly forward riding position.

Assumes about 30mm of suspension sag once seated. This is an approximation from category-typical geometry, not a measurement of this bike or of you - sit on one before you buy.
