Model-Year & Chassis Generation Notes
Debuted in 1997 as T595 before adopting the 955i badge; 2002+ second-gen engines jumped to 149 hp, returning to a single-sided swingarm for 2005–2006.
Oil & Clutch Mechanical Engineering Note
955cc inline-triple crankcase takes 3.5 L of SAE 10W-40 or 15W-50 JASO MA2 synthetic; inspect plastic fuel-tank quick-disconnect couplers for embrittlement.
