Heyy Peeps

I have a Yamaha WR125R brought it in March this year. Just wondered where the restrictors are on it and if the exhaust has any baffles that i can remove??

In the centre of the engine is the piston this is the engines basic problem as its only 50 odd mm across.

Quart from a pint pot sums it up, that engine is giving what its designed to give, noisy filters and exhausts make it 'SOUND' faster but basically your getting all its got to give without spending a lot of money for tiny gains that will destroy reliability and economy.

Use properly and enjoy, top speeds on tarmac is totally wrong for a WR, like taking a fireblade down the Ridgeway. Keep the wheels dirty and tolerate the tarmac and the bike will be stunning. Light, quiet and economical brilliant for laning, or looking good at the chippy. But fast, no.
