If you ever come across 142 for sale I used to own it. Pm if you want any info on it.
Have you had a look at this one (below) mate? Looks like it could be a good buy!

Not sure on the rear shock, can't imagine it would be that expensive though.
To give you an idea on price - a lot of Trophy owners swap the rear Sachs for Koni dampers, which can be bought new for under £250.
That ones in Leicester, don't suppose you can check it out for me lol JK
Not sure I'd dare mate. Pretty tempted myself
Seems like you got off, i think any trophy going for around that price is going to have issues unfortunately
