Rider Profile

Best ForBest suited to intermediate or experienced riders who appreciate a characterful, slightly quirky Italian air-cooled twin rather than outright modern performance.
PurposeA sport-styled roadster built for spirited backroad riding and weekend blasts rather than racing or long-distance touring.
Rider FitThe low seat height and moderate dry weight make it manageable for riders of average build, though the sporty ergonomics and air-cooled twin vibration reward a fit, engaged riding style.
CharacterHas a raw, mechanical charm with a torquey mid-range twin engine that rewards deliberate, involved riding over sheer speed.
Not Ideal ForNot a good fit for riders seeking plush comfort, pillion-friendly touring capability, or off-road versatility.

1998 Laverda 668 Diamante Rider Ergonomics Assessment

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

Feet:

At 760mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 1998 Laverda 668 Diamante, with a cramped knee angle of around 65 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.
