trident_special Posted April 28, 2009 Report Share Posted April 28, 2009 Hello folks, I've recently purchased a 1998 ZX7-R track bike, it however came with knakcered tyres that I would like to change, am I correct in assuming that originally the bike wore a 190 section rear? Am I also right in assuming that lobbing a 180 on would be a bad idea? I also have a 1993 ZXR750R which came with a set of spare wheels, would the spare rear work on the 7R?

lorenzo Posted April 28, 2009 Report Share Posted April 28, 2009 Don't know about wheel swaps, but going to a 180/55 on the back feels really good. I test rode a handfull of zx7r's a few years back and some can feel very laboured, like turning through porridge, others feel lovely. Using the set-up guide posted on here a bit back and this tyre size has made my bike feel really good. Not that it's ever going to be a modern 600 or anything, but it turns well while still feeling really planted. Great stuff. Link to comment Share on other sites More sharing options...
kwakbiker Posted April 28, 2009 Report Share Posted April 28, 2009 Just raise the rear 10mm....steers lovely then Link to comment Share on other sites More sharing options...
Mrdrink Posted April 28, 2009 Report Share Posted April 28, 2009 the front is a swap between the '93 and the '98 but the rears are different. the '93 has a 5.5inch rim and the '98 has a 6incher. put the rear ride height at its max and drop the forks through the yokes 10mm. it will transform it. put a 190/55 tyre on the back.

trident_special Posted April 29, 2009 Author Report Share Posted April 29, 2009 So would you confirm that sticking a 180 on to a 6 inch rim is a bad idea? Link to comment Share on other sites More sharing options...
Mrdrink Posted April 29, 2009 Report Share Posted April 29, 2009 So would you confirm that sticking a 180 on to a 6 inch rim is a bad idea? Its not a bad idea as many prefer the 180 as it sharpens the steering. i look at it this way....the difference between a 180 and a 190/55 is so close that many wouldnt notice it. its a case of larger contact patch over maybe sharper steering. ive ridden both and i use the 190.

eddie Posted May 1, 2009 Report Share Posted May 1, 2009 I have a 180 on a 6" rear on my 750K1, feels no better/worse than the std 180 on a 5.5"rim. More concerned about the naff rear suspension, and the contact of Al tank and family jewels.................................. Paul Link to comment Share on other sites More sharing options...
