Best for
Best thought of as a street-oriented big single, blending light off-road styling with practical, everyday road use rather than serious touring or racing.
Built for
It has a relaxed, torquey single-cylinder feel that rewards smooth, low-effort riding rather than outright speed.
Not ideal for
It is not for riders wanting high-speed highway cruising, serious two-up touring, or genuine technical off-road capability.

At 845mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with balls of both feet on the 1999 Honda SLR 650, with a cramped knee angle of around 75 degrees and an upright 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.
