Rider Profile

Best For	Suits riders with some prior experience who want a torquey single-cylinder naked without overwhelming power delivery.
Purpose	Best suited to everyday street riding, commuting, and weekend fun rather than long-distance travel or serious performance riding.
Rider Fit	A moderate seat height and light-for-its-class weight make it manageable for riders of average to shorter stature.
Character	Delivers the characterful, thumping feel typical of a big single-cylinder engine, with straightforward carbureted mechanics and an air-cooled simplicity that appeals to riders who like unpretentious machines.
Not Ideal For	Not a good fit for riders seeking high-speed touring, passenger comfort over distance, or off-road capability.

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

Feet:

At 740mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2006 Sachs Roadster 650, with a moderate knee angle of around 110 degrees and a forward-leaning 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.
