How Imprtant of Engine Valve to Motor Sports?

There are many motorcycle enthusiasts in the world, they have high requests on the engine valve, better engine valve has better speed and NO. they are focusing on the engine valve quality when they choose a motorsycle. a motorsycle sayings:

It was a sweltering afternoon on NH45 on the outskirts of Chennai when I first rode the Apache RTR 160, back in 2009. Almost nine years hence, that ride still brings back fond memories of some zippy overtakes and the rev-counter dial tracing a glorious semicircle almost up till the redline.

Fast forward to a mercifully temperate day in 2018, in a controlled and thankfully much safer environment on TVS’ test track in Hosur, and much of that zippiness and handling is around, albeit with a lot else that has changed. The new Apache RTR 160 4V heralds changes, both under the skin and out.

What is variable valve timing?

Variable valve timing is the process of actively altering the time at which the valves open and close. Due to the high-revving nature of most motorcycle engines, it’s impossible to create a single cam profile that delivers decent torque and top-end power, while meeting emissions regs.

VVT lets firms advance or retard the opening of the valves to tune the engine more accurately across the rev range. Early systems operated one timing below a particular engine speed and another above (as on the early VFR800 VTEC) but modern systems continually adjust valve timing through the entire rev range.

BMW’s cars have taken this further to incorporate variable lift in a system called Valvetronic. This enables near infinite valve adjustment and negates the need for a throttle body to control engine speed.

For common engine valve manufacturing, different standards are requested, therefore, high quality engine valve manufacturing machine can produce high quality engine valve, so even the motorcycle engine valve.

How the motorcycle engine valve affect the running speed?

1, Better engine valve is good on opening and closing, at meanwhle save the fuel.

2, High quality engine valve has long life,especially the engine valve is a kind of easy consumable products.

3, Good motorcycle engine valve making is exquisite, it will match with your motorcycle engine perfect, then good to your motor.

So, when you buy a pair of engine valves, pay attention on the engine valve manfactufing process. like how they are upseted? how the grinding quality and so on .
