2018 Yamaha Bolt R-Spec Totalmotorcycle.com Features and Benefits
///Engine
• Blacked out, 942cc, air-cooled, SOHC, 4-valve per cylinder, fuel injected, 60° V-twin power plant pumps out impressive power & torque. Maximum torque is reached at 3,000 rpms, for relaxed cruising performance.
• SOHC, pent-roof, 4-valve cylinder heads.
•4-valve design optimizes breathing efficiency & overall engine performance at all rpms
•31.5 mm intake & 28 mm exhaust valves use friction reducing single valve springs
•compact pent roof combustion chamber design & optimized squish area forces the fuel / air mixture toward the centre of the combustion chamber for more complete combustion & excellent power with reduced emissions
•25,000 km valve adjustment intervals
•Specially designed roller rockers activate the valves.
•Y shaped roller rocker arms allows a greater amount of valve lift without causing excessive camshaft wear & friction
•slipper portion of the rocker arm utilizes a needle bearing for reduced camshaft wear & reduced sliding resistance (friction)
• No fuss, traditional air-cooled engine design.
•cylinders have a tapered “V” appearance to highlight the V-twin engine design
•cooling fins have been optimized for reliable cooling even in stop & go traffic
• Automatic cam chain tensioners reduce mechanical noise & simplify maintenance.
• “Liner-less”, ceramic composite-plated cylinder bores.
•ceramic coating sprayed directly on the aluminum blocks, eliminating the liners & reducing weight
•excellent heat dissipation for consistent power delivery
