yup, those tires are all right.  140/90/15 fits fine.  Probably the most common size rear tire people run.    (Stock is an oddball 140/80/15 - too hard to find. )


you can put a "tubeless" tire on our rim, you just need to use a tube .  


(I have put 4 or 5 "tubeless" 140/90/15 rear tires on my '07 since the stock tire wore out)


If you have Dunlops on there now, check and see what size they are.  I think a lot of guys run D404s and 140-90 is probably as close as you can get.  


best practice is to get a new tube too, though i have reused tubes without incident

rebeats are fine, but i'd stay away from retreads

Get tubes from the same place you get tires.  You can get tubes at just about any motorcycle shop that sells tires if you don't want to order them along with the tires.  Your local shop will be happy to make the sale.

It's always nice to at least be acquainted with the local shops.  You might need them one day and you'll know who is good and who to stay away from.

The local guys have a pretty hard time of it in lots of places and deserve our support when we can give it to them.

I was also looking at these. a local shop quoted me front 120.97 and rear 179.97 and 68.00 per tire to change to bring the bike in. I was going to get the tires on line then just have them change them and rotate and balance. probably just do the front one first then back one later

OK what kind of tubes should I get and can I get the spoke protector online as well?
