Special slits make power easier to manage
When an engine is at high RPM, heat concentrates at the center of the engine head and thermal expansion occurs in that area. Choosing the right clearance for the piston and sleeve is a basic of racing engine design. When the engine is cold and cranked by hand, you can feel the piston getting close to the dead center of the shaft top and its tightness. Sleeves generally narrow towards the top and reduce the area that produces maximum efficiency. However the unique design of the X312T uses slits (patent pending) in the lower edge of the sleeve to widen this area, and while keeping the ideal clearance between piston and sleeve maintains compression. The nearly perfectly straight sleeve reduces loss from friction. The end result is high power throughout the range, better fuel efficiency and shorter break-in times.
◎ Ultra-fine precision machining and Nikasil coating
Interior walls of the sleeve are coated in Nikasil that leaves ultra-fine oil particles on the surface. Even under high heat, air-tightness and low friction are achieved while stable stroke range is maintained, even under severe loads. This also contributes to shorter break-in times. To extract the benefits of the Nikasil coating without sacrificing durability, the standard 30-micron machining was increased to an amazingly ultra-fine 0.3-micron precision cut. With the circular accuracy to match, the best possible efficiency was achieved.

What is Nikasil coating?
Nikasil is a nickel silicon carbide coating use to reduce friction in moving aluminum alloys (such as engine cylinder liners). It improves movement and cooling. |

◎ Special Slide Carburetor
A return spring is built into the interior of the throttle. In addition, the precision machining controls variation with RPM. Maintains stable intake and delivers linear throttle control.
◎ Fuel efficiency ideal for endurance racing
According to our research, the engine delivers a 7.5% improvement in fuel efficiency. When this engine is loaded on the V-ONE RRR Evo. it also achieved maximum speeds of more than 100km/h at the BOSS SPEED Circuit.

1) The flow of fuel mixture in normal engines occurs as per the diagram on the right. Fuel meets resistance through the channel and settles which causes wastage for poor fuel efficiency.
2) The X312T engine features a unique channel for free-flowing fuel mixture (patent pending). This results in greater flow of fuel into the crankcase.
3) As the mixture enters the crankcase on an angle, it doesn't contact the front of the back plate and slow the flow or alter its direction because it flows straight through to the intake port. In other engines the fuel hits the front of the back plate and rebounds to all directions reducing the flow of fuel mixture and its efficiency.
4) Fuel mixture arrives and precision intake ports send it freely into the combustion chamber. The swirl of the fuel mixture creates optimal ignition conditions in the combustion chamber. Power output is so high that you might think it's turbo-charged.
