    It's going to be a fun / work bike so will be built how i want it but to appear like Yamaha built it as a 200.

    Restorations are ok to a point but I don't want 100% authentic, rather improve a few bits along the way.

    Does anyone know the exact difference between the 125 and 200 motors? Assuming rod length etc and casing opening but anything else major??

    @nottsbiker Cranks, rods, transmissions bore stroke inlet size. The exhaust pipe exits from a different angle as well I believe.

      Thanks!

      Expected all of the above tbh so thats quite reassuring but didn't think the exhaust port came out anywhere different.

      There are some bottom ends in France for £250 delivered but cant see any cylinders for love nor money anywhere.

      Do people think the 125 clutch / primary drive etc are the same?

        @nottsbiker Yeah the exhaust might not, I might be confused with the 2RH engines from the Old school UK Spec TZR's.

              Wish I had read this a few weeks ago, just broke a 93 one with 3 spoke wheels not the spoked wheels one. One mans junk and all that I threw a full set of good Black TDR belgarda bodywork in the skip along with its seat clocks fuel tank headlamps headlamp brackets etc.

                  Mines black but looks like it's been used for target practice by some hillbillies so mines probably getting junked.

                  Looking at ebay europe at mo so will probably collect a full set over the winter from various different countries as just as cost effective as buying random panels here and having painted.

                  Out in the sunshine today sanding the rust off my frame before treating it then storing until I can afford the rebuild. Got my airbox apart as well for cleaning and randomly someone's cut a bloody hole in the battery tray - wtf for i don't know.

                    The K reg TDR125R belgarda is now a White n Pink DTR after a bit of modding to the frame it was a 3XE2 model, the wheels brakes forks and swinging arm are now on a 2001 DTR Hurricane Hanna replica

                    This is the type we decked, bike was identical only wheels fork and swinging arm were painted black

                      Ive done the conversion before on this 2002 DTR back in 2005 its just a bolt on job, this time ive removed all the unnecessary brackets from the forks.

                        If I wanted the 3 spoke alloys I'd fit the same as in your pictures but mine are the first model spoked wheels and I quite like them. Unfortunately Yamaha back in the late 80's went with an 18 inch front rim which limits tyre choice so I'm probably going to have another rim laced onto my front hub as my wheels are ready to be done now. The standard rims are aluminium so it would be a good match to put a rear on the front hub.

                        The swingarm on the later ones also suits the alloy wheels nicely but I can't make out if its steel or ally?

                          @nottsbiker I believe it's steel.

                              This swinging arm the one I have now is steel but the one on the Blue bike im sure was alloy ? Cant remember to be honest was years ago now but it came from the same type of bike..

                                I used the TDR swinging arm as it made the life easy for the wheels, its designed for the alloy wheels and rear brake,the chain tensioners etc and bolts straight to the DT frame.

                                    Probably was steel Cal, the one I have now is and its off the same type of bike.

                                          @tdrnoob Biggest clue is going to be in the part numbers.

                                          However, if this were me, I'd grab my vernier calipers and simply measure it.

                                          Then head over to simplybearings.co.uk and just buy Koyo bearings as a replacement. Cheap and easy job.
