Rider Profile

Best ForThis bike suits riders with at least some intermediate experience who are comfortable with a tall seat, light chassis, and punchy single-cylinder power delivery.
PurposeIt'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.
Rider FitThe 830mm seat height and 160kg dry weight demand reasonably tall or confident riders, though the light overall mass keeps low-speed maneuvers manageable.
CharacterExpect 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 ForThis is not the right bike for riders seeking high-speed touring comfort, pillion-friendly ergonomics, or serious long-distance highway cruising.

1998 MuZ Mastiff Rider Ergonomics Assessment

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 830mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 1998 MuZ Mastiff, with a cramped knee angle of around 70 degrees and a slightly forward riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
