Rider Profile

Best For	Best suited to intermediate and experienced riders who enjoy a light, torquey single-cylinder machine that demands active riding input.
Purpose	Designed primarily for sharp, flickable street riding and supermoto-style fun rather than long-distance travel or serious off-roading.
Rider Fit	The tall 830mm seat height and lightweight 175kg chassis suit riders of average-to-tall stature who want an agile, low-mass bike that's still easy to muscle around.
Character	A punchy, single-cylinder supermoto with a playful, aggressive character that rewards spirited cornering and quick direction changes over comfort or refinement.
Not Ideal For	Not a good fit for riders seeking plush long-distance comfort, pillion-friendly touring, or genuine off-road capability.

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

Feet:

At 830mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with balls of both feet on the 2003 MZ Mastiff, with a cramped knee angle of around 70 degrees and a slightly forward riding position.

Data quality: measured. 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.
