Today I put in some new fork seals from a KTM SX 65, 2002 to 2009 into a friends Model 213 Alpina. While it was apart I also cleaned out and regreased the steering head as it was a bit lumpy. New oil and it works very well again. Of course I had to go for a test ride to make sure it was all okay. Those sea;s fit all the 35mm Bultaco forks too. I also had to make sure my M159 still went so just happened to accidently go for a ride on it as well! Graham.
