    Yeah dunno, have they put in sealed bearings?

    Either way they use just normal seals IIRC.

              They look like 2005-2005 RS 125 Rims.

              They do not fit without modification.

              Different brakes, different swingarm different forks. All needs modifying.

                  @jonne123 Yeah you know, the Aprilia has completely different geometry to the DTR. So it's going to need fabrication.

                  The front and rear wheel need to be aligned. The front and rear sprockets need to align. The wheels need to be centralised. Cause it's from a completely different machine.

                      If money is a concern, stick with what you got and put some decent tyres on it.

                      Even Excel rims are expensive and require work. So there is no one easy solution.

                      The easiest way to do it would be to buy some nice and expensive Excel rims, and lace up your hubs to them That way you retain the original brakes and spacers and geometry with SM Rims.

                      The DTX solution, you need forks, brakes and wheels. These were hard to come by new, now it's practically a nightmare.

                        @jonne123 If you don't mind fabricating parts, then you'll need spacers and the hub carriers modified to take the bigger brakes. and a bracket made to mount the brakes to the wheels.

                        Can see the work required in my DTRE build thread as I run RS125 wheels on my DTR.

                              No, you need to centralise the wheels, rotate the tyres and also line up the front and rear sprockets. Otherwise you'll chew through rear sprocket carrier bearings in no time at all!

                                      No nothing fits, it all has to be fabricated. Even the spindles are different sizes.

                                      The front spindle is too small. Rear spindle was okay.

                                        If you have access to a machinist, the cost is minimal. But it all adds up. Hours on the lathe and precise measurements were necessary to get all the stars to align. I had to shim the rear sprocket to get it to fall inline with the front.

                                        When I took the bike in to have the tyres replaced. They omitted the shims and the rear sprocket carrier bearing collapsed shortly after. So it does have to be on point.

                                          And in summer i go to machine shop for summerwork so i can make them afterwork.

                                          And are the rims same size if you can give some measurements of the parts?

                                          How about the speedo?

                                          Does the ride quality increase
