what does your licence say ? oh and insurance as well .
why not ask your local police force and insurance company ...

But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.

Far better - and more legal - to look at you gear ratios. Most 125s are over-geared so struggle to hold higher speed in top gear as the engine isn't running at it's max torque. On most 125s dropping a tooth on the front cog will actually increase your top speed. It's counter intuitive because most people think higher gearing means higher maximum speed - which is correct but only if the engine can deliver the power to overcome the forces of wind, gradient etc.

125's nowadays are restricted by BEING a 125. Long gone are the days of derestricted 100mph 2 strokes :crybaby:
