The 16 valve DOHC monster mill has a 90x66mm bore/stroke with lightweight forged aluminum pistons and fracture split connecting rods. The camshafts are both chain and gear driven, utilizing chain for the intake and a gear mechanism for the exhaust. This allows for a narrow valve angle and for a generous 11.3:1
compression ratio.
Besides providing the power, the engine also serves as a stressed member of the frame, and Star aimed to maintain the V-boost character of the original mill. When asked, Ulrich confidently stated that it makes power like no other production bike he's ridden. This straight from the mouth of a man who's had the privilege of riding it already on the street and track. When asked if he'd layed down a 9-second quarter-mile on it yet, he just smiled and shook his head.
Call it a cruiser if you want, but the 2009 VMax has the power and torque numbers to steal the lunch money from a few of the literbikes if they aren't careful.Big titanium cans complement the overall muscle bike appeal of the 2009 VMax. The rumble coming out of the pipes ain't bad, neither.o longer solely a concept bike, the new VMax is now a reality. If you like what you see, you'd better act fast because Star's only making 2500 2009 models.
