TB Big Valve Kit – Honda Grom / MSX125 / 125cc Monkey (2014-2021)

Check this kit out!
- +1.5mm intake and +0.5mm exhaust valve kit for the Honda Grom / MSX125 / Monkey 125 (2022-Up is a totally different motor)
- Both valves are constructed out of EV8 stainless steel to provide superior strength and longevity over the factory valves
- Lighter than the factory valves. Additionally, the valve profiles have been changed to yield better flow characteristics resulting in better performance.

With these over sized valves you get the best of everything as the stainless material will long out live the stock valves, the bigger size will yield more flow thus yielding more power.
Also the lighter design will help prevent valve float providing the potential to rev higher and faster and it frees up horsepower.

Note: This kit should be installed by a professional mechanic or shop that offers valve job service as the valve seats must be cut to accept the larger valve head diameters and valves sunk deeper to allow for overlap clearances.
