Rider Profile

Best For	This machine suits an experienced rider comfortable with a heavy, powerful, analog-era sportbike that demands deliberate inputs rather than forgiving anything.
Purpose	It was built as a homologation-special sport flagship for fast road riding and occasional track days, prioritizing top-end speed and stability over versatility.
Rider Fit	At 259 kg with a firm sporty stance and 18-inch wheels, it rewards a rider with decent strength and confidence muscling it through direction changes.
Character	It has the charismatic feel of an early-80s superbike icon: raw inline-four power, air-cooled character, and dual-disc bite delivered with old-school heft.
Not Ideal For	It is not the right choice for a novice rider, someone wanting plush touring comfort, or anyone seeking a light, nimble city commuter.
