I saw that Rocket, actually owned a very nice (too look at) 300exc with heaps of suspension work done by HRh Terry Haye, I tried God knows I tried, but after one too many trip over the bars courtesy of the Pilot Discharge System, I gave up on it and bought a bike that suits my riding style, I am very ye olde MX schoole I mostly ride the rear and float the front, PDS ain’t condusive to this Hence the lack of success in SX and to a lesser degree MX. This is also why myself and many other former KTM riders are watching the new 350 linkage bikes with interest.
It’s a trade-off you could buy a postie and not worry about frequent valve checks and oil changes too…….
