Kawasaki KH125

[P.addy]

Basically, i bought a little 1989 KH125 2 stroke commuter to go to and from work, cheaper than the car and I dont really want to use the 600 given the varying conditions/lack of balls.

The rear tyre is nearly down to the limit, is it worth replacing both tyres?
2.75 18 and 3.00 18... what are these is normal tyre terms? also, anyone rate this company + these tyres?

They have both the 2.75 and the 3.00, not sure if its just a simple put them on, not sure about front and rear specific tyres etc.

Another few questions...

How do you adjust the suspension on the rear? Springs are on the side and the ride is kind of bouncy!

Performance wise, its perfect, enough for town use and keeps to 60 in the country lanes, so perfect for me, but how do I keep the performance at optimum.

Had a full rebuild 2500 miles ago (now on 19000 miles) , so its not too bad

Brakes seem horrendous, slowing from 50mph, you really do have to plan in advance! Could it be a case of just needing new front pads and bleeding the fluid.

Cheers for all the help!

Replace both tyres, they cost nothing at all.

AS for the brakes, the front is a disk but i remember from mine that it was never as sharp as the TZR.

The suspension has a little serrated edge, you'll notice on both sides of the bike, this can be turned (with the aid of some tool) to adjust the preload. You cannot change rebound or damping.
