<P> Overall, the V - Max was 2,300 mm (91 in) long, 795 mm (31.3 in) wide, and 1,160 mm (46 in) high . The engine was a tuned version of the double overhead camshaft, four valve per cylinder, liquid - cooled V - 4 from the Yamaha Venture . Along with other modifications to the engine, the compression ratio was raised to 10.5: 1, and the V - Boost system was added . </P> <P> V - Boost is a system that opens butterfly valves in the intake manifold between the 1st and 2nd and between the 3rd and 4th cylinders starting from 5,750 rpm . The valves are opened gradually to match the rising engine speed with a signal provided by the ignition system . The valves are at the full open position at 8,000 rpm . A small black box sends a computed signal to a servo motor that pulls a wire to open the butterfly valves . The V - Boost system adds 10 percent to the top power rating of the base engine . </P> <Table> Yamaha VMAX <Tr> <Td_colspan="2"> </Td> </Tr> <Tr> <Th> Manufacturer </Th> <Td> Yamaha Motor Company </Td> </Tr> <Tr> <Th> Production </Th> <Td> 2009--present </Td> </Tr> <Tr> <Th> Predecessor </Th> <Td> Yamaha V - Max </Td> </Tr> <Tr> <Th> Class </Th> <Td> power cruiser </Td> </Tr> <Tr> <Th> Engine </Th> <Td> 1,679 cc (102 cu in) liquid - cooled DOHC 65 ° V - 4 </Td> </Tr> <Tr> <Th> Bore / stroke </Th> <Td> 90 mm × 66 mm (3.5 in × 2.6 in) </Td> </Tr> <Tr> <Th> Power </Th> <Td> 197.26 hp (147.10 kW) (claimed) 174.3 hp (130.0 kW) @ 9,000 rpm (rear wheel) </Td> </Tr> <Tr> <Th> Torque </Th> <Td> 123.02 lb ⋅ ft (166.79 N ⋅ m) (claimed) 113 lbf ⋅ ft (153 N ⋅ m) @ 6,600 rpm (rear wheel) </Td> </Tr> <Tr> <Th> Transmission </Th> <Td> 5 - speed, slipper clutch </Td> </Tr> <Tr> <Th> Frame type </Th> <Td> cast aluminum </Td> </Tr> <Tr> <Th> Suspension </Th> <Td> front adjustable 52mm oxidized titanium coated rear adjustable Link - type Monocross with piggyback reservoir </Td> </Tr> <Tr> <Th> Brakes </Th> <Td> Front: radial mount 6 - piston calipers, dual wave - type 12.6 in (320 mm) discs, brembo master cylinder Rear: single piston caliper, wave - type 11.7 in (298 mm) disc, Brembo master cylinder </Td> </Tr> <Tr> <Th> Wheelbase </Th> <Td> 66.9 in (1,699 mm) </Td> </Tr> <Tr> <Th> Dimensions </Th> <Td> L: 94.3 in (2,395 mm) W: 32.3 in (820 mm) </Td> </Tr> <Tr> <Th> Seat height </Th> <Td> 30.5 in (775 mm) </Td> </Tr> <Tr> <Th> Weight </Th> <Td> 694 lb (315 kg) (wet) </Td> </Tr> <Tr> <Th> Fuel capacity </Th> <Td> 4.0 US gallons (15 l; 3.3 imp gal) </Td> </Tr> <Tr> <Th> Fuel consumption </Th> <Td> 28.3 mpg (8.3 L / 100 km; 34.0 mpg) </Td> </Tr> </Table> <Tr> <Th> Manufacturer </Th> <Td> Yamaha Motor Company </Td> </Tr>
