RC51 owners.. tire question

Not sure how many of you here have an RC51, but here's a question for you. I need a new set of tires for my SP1, and I'm thinking of going to a 190/55 in the rear. What I want to know is, can I just install it without changing anything on the suspension? Will it fit without contacting anything? How about setup, did you change anything while running this size of tire?

Go to www.rc51.org/ head to the mods section and there is a sheet on tire sizes and so on.

My bike has the Moriwaki link and a Ohlins rear with the ride height adjusted so I did a bit of swapping around when I changed tires I stayed with the stock numbers since I already had the bike up on it's nose.

I don't have an RC-51, but I can tell you that the only two parts of the bike that a "55" may touch would be at the extreme forward portion of the tire where it is closest to the swingarm. I think this may only be an issue if your chain and sprockets were brand new and your rear wheel was at it's farthest forward adjustment position. The other area that may rub is if you have a factory or aftermarket rear "hugger" fender. Sometimes there is not much room between the rear hugger and the tire.

A "55" will cause a slight increase in rear ride height, slightly increasing steering head angle and steering quickness. If this causes stability problems (unlikely) the forks can be lowerered in the triple clamps to increase the front ride height to match the rear.

Putting a 55 on a GSXR 1000 is a bolt on, no clearance issues at all, but you may wish to post on an RC-51 specific forum for more info. Someone here may have done it, but it's a relatively rare bike..........

good luck

Or go to

www.speedzilla.com/f...-general-discussion/

and do a search with "tyre (tire)" in the title, you'll find plenty of threads on the subject.

I'm going for a 180 on mine. (Cheaper)

Speedzilla is a trainwreck. If you plan on keeping the bike then the $ to sign up on ROGUE is worth it just to get to the mass of archived info on the 51.
