Rider Profile

Best For	Best suited to riders with at least some prior experience, as the big single's torquey, thumping power delivery and tall seat height reward confident handling.
Purpose	A lightweight naked bike designed for punchy, characterful street riding and back-road fun rather than outright speed or distance covering.
Rider Fit	The tall 830mm seat height and 175kg dry weight suit riders of average-to-tall stature who can comfortably manage a firm, upright single-cylinder machine.
Character	Raw and mechanical in feel, this bike delivers gruff single-cylinder charm with strong low-down torque and agile, flickable handling.
Not Ideal For	Not a good match for riders seeking smooth long-distance touring comfort, pillion-friendly ergonomics, or high-speed motorway cruising.

Feet:

At 830mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2003 MZ 660 Mastiff, with a relaxed knee angle of around 130 degrees and a forward-leaning 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.
