160 rear?

Tamburinifan · **Posted:** Wed Nov 05, 2008 3:22 pm

Anyone tried 160/60 as rear tyre?
Your impressions?
Better/quicker handling?

I have the stock 170/60 and here in Italy fitting a 160/60 would get the bike not legal for road use...
No matter, I find the handling could be improved with a fine tuning of the suspensions, rather than changing the rear wheel.

I use 180/55 in rear and i am very happy with that.... no need to change and chain DONT hit to edge of tire, cause i keep on eye to right chain tightening... I havent tested such tire ever in 907, what U are talking about. :smoke:

I wouldn't do that as the 5.5" wide rim is to wide for a 160 tire.
The heels of the 160 tire spreads more in a 5.5" so the profile will be more flat, so more like the shape of 170 or 180 :mrgreen:

So overal there isn't much gain.
fine tuning suspension could be more rewarding

What Ducbertus says is right. The wheel is too wide.

Gert,
I similarly run a 170/60 and the handling is fine; my rear is cranked up hard (probably too hard, actually) and this makes the bike steer a bit quicker. I don't find the 907 as sensitive to front-end feed-back to the rider so I don't push it as hard as my 900SS.

The poor old 907 doesn't have the refinements of the newer bikes (like rake adjustment) to take full advantage of the tyres - and I believe the 160 might be a bit narrow on the rim.

The 1990's brought wider rims into the world - it seems a step back to try to fit the narrower tyre. The tyre footprint is reduced (so less traction / more slipping & sliding) also consider you might also lose some ground clearance.

OK, thx, guys.
Just asking, 1 or 2 have done this on other bikes but I remember now
the M900 guy also switched rim to 4,5".
170 stays.

Thinking, that 180/55 (if chain is in right tight) and 170/60 fits to 5.5" rear rim, but 4.5" rim needs 170/60

Gert, i make measurements, what U asked, at weekend but i have lost Your private mail address, so send it to me! To: finnpaso@gmail.com

I have a 6" magnesium rim laying around. maybe with a 190 tire. I think this will look brutal

I quess, that, problem with such wheel/tire will be rubber worn out from chain side... :mrgreen:

Fatter rims/tyres than those who perform best is only for
impressing teenage girls at the village square.... :thumbup:

to avoid the chain hitting the tire the chain has to move outside. just as simple as that.
