Rider Profile

Best For	This bike suits an experienced rider who appreciates classic, mechanically intricate machinery over modern performance.
Purpose	It was built as a prestige grand-touring roadster, showcasing an exotic in-line six engine rather than chasing outright speed or agility.
Rider Fit	At around 249 kg with an air-cooled six-cylinder engine and dual front discs, it demands a confident, moderately strong rider for slow-speed maneuvering.
Character	The 900 Sei is a charismatic, smooth-running collector's classic prized for its unique engine sound and engineering rarity rather than aggressive handling.
Not Ideal For	It is not suited for riders seeking modern sportbike agility, off-road capability, or high-speed track performance.
