Hi all,
My first 1000f needs a back tire. Factory says 190-60-17, bike has a 190-50-17 now. Can i go bigger, as in wider? Appears to be room in the swingarm.
Suggestions?

 

Until you get a lot of miles under you, stick with stock. The pros and the crazies are the only ones who beat this one to death. 90% of the riders out there (I made that number up, by the way) will not be able to tell the difference in ride quality/performance.

Welcome!, East Greenwich huh? I grew up in N.Kingstown. I would say stick with the stock size normally cheaper, and on my 94 i wouldnt think there is alot of space. What year bike you got?

 

1991 cbr 1000f. Just repaired my sons 1994 cbr600 after a crash. Decided I liked his but needed bigger, im a big unit. Been riding since I was 5, on and off, 45 now. I will update my info now that I can post, and load some pictures. Figure a 55 is on there, so I run that again. I'm sure to have loads of questions so nice to meet you.

Welcome Rhodeislander , moved this to the main thread, anyway 170 was stock from
89 to 1996

160 for 87 & 88

Quite a few of us moved to 180's and one or two to the fatter 190's

So up to a 200 , ya might want to consider the chain getting in the way !
anyway going higher than 180's as has been discussed here a few times
seems to make the bike incrementally slower to lean and turn, so it depends
what your requirements are.

 

Welcome Rhodeislander

89-96 had 170 as standard, not 190.
190 makes the steering heavier - 180 is the best tyre for these bikes.

Welcome to the asylum !

 

I've stuck to the 170 standard on mine but might try a 180 one day. I wouldn't go wider than that though as I think you'd stuff the handling up for the sake of the look of the bike from the rear, which you can't see when riding anyway. Just my two cents mate.

Oh and, welcome to the forum! Drop in the 'Saloon' for a few beverages and to talk some bs...everyone else does.

 

I noticed the center had a flat spot develop on the current 190. The outer edges are like new, almost like the tire cant connect at the outer edges, and a ridge has formed. I guess the simple was to explain is, the bike dont use the outside on the fat tire?

Ok, so 180 it is.

I guess this is the place for general questions so here goes. The chain looks way too long, and is slapping. I want to go for the entire set, front,rear and chain. I see 16t,17t combo's. I'm a big guy 290lbs, and she's is an old girl 40K. Should I choose a lower ratio to offset the above factors? Am I thinking too much into this?

I'm looking to restore her over the winter, but for the summer, change the rear tire(plugged) and chain set.

The past owner said the bottom stem bearing was shot, he said it was centering? Dont know what that means. I assume a flat spot or bad bearing in the race. Is this common? I see alot of new bearing sets on ebay? I assume thats why.
How much of a PITA is that to do? Never done that job before.

I have a ton more questions but these are most important to me.
Thanks in advance guys!

Same physical demographics as myself ....well you maybe a little lighter

Stock is best man 17/42.

having said that on occasion on my 1990 I run a 16 up front and a 44 rear (fast accel)

also run an 18 / 44 and at times an 18 / 42 (both for highway and touring etc)

My 1993 bike tho I keep stock 17 / 42 the way nature intended


Good choice with the 180 ........ it's "the way to go imo"

 

Any input on the stem bearing? Is it common? Big job?
