  • 92 katana 750, easiest way to get a wider rear tire?

    Recently picked up a 92 750, and was wondering the easiest way to swap a larger rear tire than the 150 on it now. Looking for 170-180.

    First welcome to KR, search feature works well or wait for kreylin to pop in.

    He has done this mod as well as makes custom swing arms to fit the wider tire and here is a link to his build thread http://katriders.com/vb/showthread.php?t=96736 .

      A post kat wheel is 4.5", will fit up to 170. With the pre 750 swingarm, you should be able to work out the brake arm clearance to squeaze a 170 in. I know a 160 will work.

      Modd the existing swingarm wider by cutting/welding for the 180.

        Thanks, I can't get the search feature to work on my phone or id have done that. My tires a 150 and doesn't look like there's much room for any more or it would hit the swingarm

          The brake arm will be the issue. You can squeeze a 170 in there with a post wheel.

            What is your reason for a wider tire? If you want more choices and stickier rubber, ok. Otherwise, the 150 is perfectly fine. I have yet to over-tax any of my 150s on my 89 750, in spite of some pretty spirited riding.

              Looks.... that's 99% of the time the real reason.

              The other 1% had done an engine swap and want something beefier for the added HP...

              It doesn't stop with the Kat... I've recently joined a local sportrider facebook group, and I'm not surprised to see that 1 in 10 posts is about putting an oversized tire on their newer SS bikes even...

                  I know I've said it before, (swap the carriers too) and that was based on a thread with a swap someone did and posted pics... but, I've since been able to do some research and other swaps with feedback... I don't think the carrier swap is necessary.

                  I think the OP who posted the rub issues... had wear issues with the rubber cushions. I've not been able to recreate the issue they posted. The hub spacer is the same pre/post kats. I don't think it's necessary now.

                  Any counter info to clarify it is?

                    You know, I think I misread with the spacer. I'll be having my post Katana rim swapped in next week I'll know for a fact then

                      Sounds great.

                      The specific issue posted prior was the hub fins rubbing on the inside wall of the wheel. My post wheels (3 diff ones) with each having it's own set of rubbers won't let the carriers anywhere near that, so... I don't know of any other reason it would be an issue.

                        So the bike shop said that the post 2002 Katana 750 rear wheel bolts right up with only one small problem.

                        The rotors are different, my pre Kat has 4 bolt rotors and the post Katana has 5 bolt rotors. After sourcing the correct bolts and rotor it was a direct fit with no clearance issues with the 160/60 /zf17

                        I go to pick it up tomorrow so If anything changes I'll be sure to update it.

                          Yeah, the rotor is a known swap. If using the post kat carrier, you would need to either use the post Kat spacer on the left side or cut the bolts down. Pre kat carrier doesn't have that specific issue.

                          Definitely check the clearance for the sprocket bolts to swingarm. Personally I think upgrading the left spacer to a post sized spacer isn't a bad idea.
