Hi from an ex-TTR250 owner and sadly only registering on the forum to sell a new clutch cover gasket that I found in a garage clear out - check out the for sale section.
I'd have another TTR250 if there were more green lanes near me (I've ridden most of them in South Derbyshire, Leicestershire & Nottinghamshire - and there aren't that many) and if the TTR250 was actually.........350cc, it could just do with a little more 'go' - don't get me wrong, I thought the suspension and the carburation for pottering about in the dirt were fantastic.
But I've now got something with a DRZ400E engine (CCMR35) and that would be the way to go for me if I wanted to go green laning again.
