    Everyone to there own, but I like the early 89 90 91 bikes. Its hard to find them in good original condition now but they are the best for me. Im sure others will have there say.

      You could prize it away from me for the right money, 91 model 2 owners from new. Completely restored from the ground up.

        @natnice Bikes up to '98 have less restrictions and therefore more grunt than post '98 models. But it's not that hard to de-restrict them and restore their full power. Also I believe the early models have the more desirable 3MB head? DTR's didn't change much over the years, with mostly cosmetic changes introduced by Yamaha. But others may have more knowledge on that than myself?

        They kept the enduro look up until 2003 and then they added the SuperMoto look with the DTX and RE models. The RE could be bought with either enduro or SM trim. The SuMo has better brakes and wider wheels/tyres for more stability at speed. It all depends on which look you prefer?

        I would make your choice and then just find the best example with low ownership, that's currently available, dependent on your budget of course. Scrimmy's bikes are always mint BTW!!! 😉

            @cyber-ninja Yes I have had my eye on the DTX for the most part when looking into this type of bike if I go for this it will have the 3MB head already? Which will tie in nicely with some other mods if I am correct?
            As derestricting goes on the DTX I heard it's just to earth a wire running under the speedo don't quote me though!
            Thanks for the reply!

              @natnice I'm not sure which head the DTX's have? With derestricting there's also some restrictions in the exhaust pipe, so you will need to remove those or fit an after-market system like a DEP, Giannelli or Big One etc.

              See Scrimmy's full de-res guide here;

                DTX/RE Is the green and black wire then they're full power.

                They do have a restriction in the pipe, aftermarket pipe sorts that out.

                  All I've done to my 'X' is earth the wire and a full DEP exhaust. -1 tooth on the front sprocket as well. Went to a 2 stroke rally at the weekend, everyone kept asking me what I'd done to it, expecting big bore kits etc 🤣

                            Nah, if you can find an old one thats not been derstricted it was a doddle. Turn the powervalve round to fully open and put the peg and cover back on, exhaust off 3 spotwelds holding the restriction tube in the manifold wip that out exhaust back on job done.

                              I will probably be keeping it for a while now the Black one has gone to be honest.

                                  @natnice Yeah nice.

                                  For that sort of money you should get a lovely example.

                                  More is going to be less with these ageing bikes.

                                  Pay a little bit more for a bike that is in better condition, and it'll save you in the long.

                                  But I suppose it all depends on what you want it for. These bikes are appreciating classics, if you are going to do lots of byways then it's nice to have an example which has been used for this purpose before.

                                  If you it's a sunny day rider then a nice restored one will suit you.

                                    Exactly my thoughts, I am looking to use it quite a bit and personalise it along the way of course.

                                      Update!!
                                      I've got my eyes on a bike and I got 2 questions.
                                      The plastic shielding the front two forks can they just be removed or do I need different forks?

                                      And also the wheels from the images provided would you be able to tell if the wheels could fit SM tires instead?
                                      Sorry for the novice questions haha I'm knew to the DT

                                      Thanks
                                      Nat

                                        The fork gaitors are crucial to preserve the longevity of the fork seals.

                                        You can replace them for neoprene socks.

                                          Update!!
                                          I've got my eyes on a bike and I got 2 questions.
                                          The plastic shielding the front two forks can they just be removed or do I need different forks?

                                          And also the wheels from the images provided would you be able to tell if the wheels could fit SM tires instead?
                                          Sorry for the novice questions haha I'm knew to the DT

                                          Thanks
                                          Nat

                                          @natnice That's a nice example.

                                          I ran my bike without fork gaitors with NPs. But obviously they are their a reason as @Calum stated.

                                          DT's in enduro form run a 21" front wheel and an 18" rear wheel. SM wheels are 17" so you would need to replace them if you wanted the SuMo look. Or you can stick with the stock wheels and just run road tyres, personally if you want the SM look I would just buy the DTX version. As that way everything is factory designed and needs no faffing about etc. Because if you want SM wheels and brakes you will need to swap the front forks, wheels, brakes from a DTX and ensure that everything lines up perfectly including the calipers, discs, sprockets and chain. Which will mean custom manufacturing some brackets and spacers to get it all to fit. So unless you are prepared to go down that road, then it's a choice of enduro or SuMo???

                                          SEDUCED BY THE DARK SIDE!!!
