**Compatible with BW'S R125 made by Taiwan YAMAHA released in June 2015..
Hyper valve for BWS R125.
It is a part to reduce the pressure resistance generated in the crank case and to eliminate the power loss, and it is a product that can change the characteristic easily and at low cost.
By installing it into the blow-by reduction pipe, the effect of engine brake reduction, response improvement, fuel consumption improvement, good starting performance and oil life extension can be obtained.
●Engine brake reduction
As shown in the engine brake characteristic comparison graph above, the deceleration time by the engine brake when the accelerator pedal is returned is different by about 1 second between 80km / h and 60km / h.
It means that the engine brake is less effective and the time to slow down is longer.
The same effect can be obtained on all small displacement bikes by installing.
●Improved response
By decreasing the resistance of the pumping pressure in the crank case, the engine start-up becomes lighter.
●Increased fuel efficiency
This reduces wasteful combustion and improves fuel economy.
●Good starting performance
Engine vibration is reduced, and the loss that occurs at the time of starting is reduced, and the starting performance is improved.
●Extended oil life
Since the load on the engine is reduced and the damage to the oil is also reduced, the oil life is extended.
It can be installed by simply inserting it into the stock blow-by reduction pipe without any modification.

Can tell there is less engine braking. Idle seems to be steadier as well. No real increase in power. To early to tell if I am saving any on gas. Good product overall.
