My GSXF I picked up on Saturday has mis-matched tyres (D205 on rear, Contiforce on front) that make the bike feel terrible. Naturally I want to change them straight away and a popular tyre choice is sticking a 160/60 on the back instead of a 150/70. The Katana website (USA name for the GSXF).

Now..here comes the confusion, some have said that I need to match the front profile with a 120/60 instead of a 120/70...but i seem to recall some of the bigger bikes having a 180/55 with a 120/70?

Can someone please advise!!

you dont say your rims sizes???

you dont say what dia 17"??????

i dont understant, do you mean if you fit the 160 you need to go down to a 120/60 on the front , the theory being the 4.5" rim will pinch up the 160???


IMHO the bad handling wil be caused be the awfull conti front. Get rid of that now.

D205 is a good solid tyre get a front 120/70 to match.

17 inch rims..rear is a 4.5 inch jobbie.

The Americans seem to think that it is important to have matching profiles front and rear..ie...60/60...but I think this is maybe not the case due to sports bikes having 55/70 combinations.

Basically the bike is a faired Bandit 600 with a 750 engine...same rims etc.

Sorry i dont understand the logic if you fit an oversize rear (for starters 160 is fine on a 4.5 rim anyway) then surely you want a rounder (ire higher profile tyre) to match it (somethin like 120/80, not a less rounder (smaller profile) one (120/60)????


Naaaahhh

just get rid of that 'orrible discusting Conti. if you match it with d205 in stock 120/70 and see where you are. 160 is fine on a 4.5 inch rim.

Ta!
Its just that its £88 for a new 205 front...or £160 for a pair of 207's..and I will need a rear within a month or two anyway.

I think I will get a pair of 207's

Look mate. Tyres is like trying to sell someone a religion. what works for one personis hopeless for someone else, theres too mnay variables.

You just got to work it out for yourself. Starting with a clean slate and stock sizes sounds very sensibile to me.

Try this link for some good advice, which includes your bike. Unfortunately this site isn't updated very often, and he doesn't have the latest tyres reviewed, but it's a good starting point if you're pondering about chaning the profiles.

Wot KFZ sed! FWIW, I wouldn't dream of changing the profiles until I'd experienced the bike with the recommended sizes and profiles fitted, in a quality tread from Metz, Dunlop, or Bridgestone
