Does anyone here in the US offer rear wheel broadening? Would love to eventually get some 200 tires in the back ... | ||

bitz4buells has a 240 kit? it looks cool, but not sure it would handle well. 180 seems to be perfect. | ||

Sandy Kosman can do it. http://www.kosman.net/weldup.htm | ||

I've heard it is possible to put a 190 on the stock rear rim. Is this true? I am curious to know. | ||

Yup, my brother did it and he hasn't lost any handling. | ||

You may not lose handling if you are not looking for handling. The 180/55 is a good tire without slowing turn-in. The extra width WILL slow down the turning - there is no choice in the matter. If you like look of the fat rear, I say go for it but don't let yourself think you are not slowing down the turning capability of the bike. | ||

Slaughter- thanks for sharing the +/-. Is the slower turning noticeable? (Message edited by lpd22 on May 01, 2005) | ||

I think the only time you will really notice the difference will be at the track. His bike still corners really well, but he isn't going 120 around the corners either. | ||

Correct me if I'm wrong but handling & turn in speed are not the same right? I'm sure the bike will be stable with either tire but assuming you ride deep into the corner than quickly dive & go, I'd say 180 is the best bet. If you start your turn early & try to be smooth as possible than maybe the slower turn rate doesn't matter too much. Am I on to something here or am I way off?? *paging Mr. Slaughter; please pickup the white courtesy telephone*  | ||

Turn in speed is part of handling. Going to a 190 won't be noticable for the average rider out there, it may feel different at first but if you aren't the type to be getting rid of your chicken strips every weekend you won't notice a thing. Going to a 190 won't make the rear look alot fatter, and in some cases, a 190 won't fit. I was sent one by mistake and tried fitting it, without being on the rim I still couldn't get it to clear between the belt and the swingarm so I didn't bother trying to fit it, I mean hell, they did offer to let me keep the $20 higher tire since it was their mistake, why not give it a try since it was going to get thrashed in commuting  | ||

I saw the broadening services of R&R in Germany - and it sounded interesting - according to them no problem fitting it on a XB besides the belt cover http://www.r-r-customizing.de/seiten/shop_eng/index.html look under broadening wheel section | ||

Been off line here a while. Hurrying through this at break here at work... the following are opinions - not backed up by engineering (I'm too intellectually lazy right now) The larger cross-section of the tire means you just have more to overcome in tipping over the bike - basic geometry PLUS rotating mass. For a bike in the turns, there is no advantage to the fatter rear - ESPECIALLY if you're not seeing the kinds of corner speeds where traction is an issue. I'd say ZERO advangage - outside of looks (and I can't argue looks). I have slid the racebike at varying speeds from zero off the line on cold rubber to maybe 130... (a couple times even without crashing too!) and having a fatter tire doesn't put enough more rubber onto the ground to give any traction advantage that would overcome the reduction in turning response. Personally, if you don't plan to push the bike that hard, if you're not slipping the rear tire off the line in drag racing, then the only reason for the fat tire is cosmetic - the other arguments are academic. I cannot say that going with the wider rear because of the way it LOOKS is a bad call (I did that on my nearly stock Ford Pinto in 1975 because the wider rear tires looked cooler than the stockers) - but that is just a costmetic choice. IF the fat rear can clear the swingarm AND IF you aren't looking at handling qualities, there is no harm in putting on the bigger rear tire - just remember the tire grows maybe 1/4 inch at speed so make sure it'll clear the swingarm. You also have to raise the front end a corresponding amount to compensate or you're really going to be dealing with the usual problems associated with a steeper front end with the reduced rake angle. I'm sure I'll proof-read this later and think of more stuff. I'm no expert, just trying to learn all I can before I die of old age. | ||

Holy crap, on that www.bitz4buells.com they have a XB Turbo conversion kit http://www.bitz4buells.co.uk/cart/index.php?main_page=product_info&cPath=74&prod ucts_id=226 And they have a supercharger kit from Hillbilly motors, cool Awesome!!!!!!!!! (Message edited by sweetp411 on May 05, 2005) | ||

boyoboy 240 on the rear is insane. Thanks a lot Slaughter for all the helful info! (Message edited by mikeguava on May 05, 2005) | ||

There are people who cut/re-weld wheels that I've seen advertising in the back of Roadracing World. Don't know if RRW is available in many areas but many bigger booksellers and magazine shops sell it. | ||

Just got a present of a part worn (slightly) 190 section Diablo Corsa Pro SC0 (i.e. supersoft) and I'm going to try it on my XB9r I'll post the results asap. |
