        Early DTR125 come with power valve pinned into place. I spent £180 all in for my servo, bush, pulley, pulley body, cover, new cables & rubber servo cover. They can be found cheaper but you have to wait and look around. Do Not get conned into buying a 5 wire servo!! I almost had it done to me advertised falsely. You need the 3 wire servo...

        Nothing else will compare to having it fitted. You have the full power and the low end usability of an enduro. When my bike was pinned open you had to rev the balls off it and slip the clutch just to pull away...

          It wont bring in lots more servo motors to choose from but the early TDR125 model code 3SH also uses the same 3 wire motor

          Belgarda TDR's were primarily sold in Italy, France and Germany so have a look at those ebay sites as well as the UK one

            That’s actually really good to know!

            The bloke I got my setup off of said he trolled the European markets for them, but it was starting to dry up last summer. I Don’t know if true or just hiking up the price. The only ‘kits’ I’ve seen on fleabay lately have been 5 wire servos though...

              I bought one last year for my TDR project as it strangely didn't have one when I got it and from memory it was around £45 from ebay UK which I thought was reasonable
