The brand new TR-1 High Output 1049cc, 3 cylinder, 4 stroke engine powers all the VX models (excluding the new VX Cruiser HO and VXR). This ultra light, compact, liquid cooled engine delivers class leading performance. The engine is light, compact and packs a real punch offering lively acceleration and great top end power, whilst the electric fuel injection delivers a smooth drive with low fuel consumption and minimal exhaust emissions. Yamaha’s major breakthrough with the new TR-1 engine, which replaces the MR-1 model that first appeared in production WaveRunners in 2002 and was Yamaha’s first four-stroke power-plant. That motor was based on the R-1 motorcycle engine and had four cylinders with five valves each. The new TR-1 has virtually the same 1 litre displacement but has three-cylinders with four valves apiece and weighs just 160 pounds; a 20 percent reduction. It’s also 40% smaller and 13% more powerful. One of the major benefits of the engine’s smaller footprint is it leaves plenty of room for maintenance.
