Hey guys

The rear on my 1986 GSXR-750 will be due to be replaced soon, what do you fullas reckon for tyres? Im using it for daily commuting and weekend blats, not planning to go to trackdays at this point.

Its currently got pirelli sport demons, i know bridgestone battleaxe tyres will also fit.

Any ideas?

The tyre sizes are 110/80x18 front and 140/70x18 rear.

Cheers

Sports touring tyres are what you need. Avon Storms would work brilliantly for you.

Next question please.

Not quite Mr Hitcher.

www.avon-tyres.co.uk recommends these for the slabbie 750:

GSX R 750 F, G, H (1985 - 1987)

Front Tyres» Roadrider (http://www.avon-tyres.co.uk/motorcycle/?page=tyres&method=showtyre&id=6)
Size 110/80-18 58V
2.5 bar (36psi)
Rear tyres» Venom (http://www.avon-tyres.co.uk/motorcycle/?page=tyres&method=showtyre&id=1)
Size 150/70B18 70V
2.9 bar (42psi)

Interesting that, although Avon have Storms that will fit, they don't recommend them. I wonder why?

Perhaps they haven't updated their web site for a while...

I'd suspect the storms are a radial and the venom and roadrider are crossplys, like the bike came out on....
I'd prolly just stay with the demon's...

I have an '86, which is was upgraded from the '85 model by recieving:
1) 25mm longer swingarm
2) Radial tyres out of the factory

The pirelli's do the trick, its just that im not the biggest pirelli fan and would like to find something that can do the job a bit bettererer.

Avon storms you say? I will look into it. Im gonna be taking the wheels to cycletreads to be fitted, do they stock avon? I know they have pirelli's, bridgestones, conti's and a bunch of others, however i don't recall seein' avon brand stuff there.

Is there anything from Conti worth looking at?

EDIT: just took a look on avon website, and a few posts on here about avon storms, looks like they might be the go :) Hope they ain't obnoxiously expensive... (bridgestones are $180 front and $220 rear without fitment)

A lot of people including me are happy with the softer conti tyres at the moment (eg sport attack and race attack) so hopefully the road attacks are good too.....

Kerry at motohaus is probably the best for the avons?

Theres a bit of discusion on conti roads here http://www.kiwibiker.co.nz/forums/showthread.php?t=68095&page=2

Sadly, the only conti's that will fit the oil boiler is the TKV series

Got nought but good to say about the Storms. You'd do well with them on, especially with the sort of riding you're doing.

Conti Road Attacks, Z6s, and Pilot Road 2s are all good too if you can get them in your size.

You might also look at Metzeler's reissued Z4s as well - could suit you to a tee and not a bad price too.

They sold and fitted a set for me not three weeks ago.

Tell me more Mr Hitcher. The RF's looking a bit shabby treadwise lately...

For a 120-70 17 and 180-55 17 set, the cost was $520 on the bike, GST inclusive.

Well, looks like the bike will be getting some avon storms the second my currency has recouperated itself (the rear has about 2.5mm of tread left)

$550 is about $200 more than the demons, but i don't mind paying more for good tyres. Ill make a write up once they are on the bike and i have done some miles.

Thanks for the help guys

I look forward to that writeup, my '87 slabbie needs a new rear as soon as the engines back together :pinch:

Stupid 18" rims >.< tempted to try a swap..

Don't bother man, leave it stock.

However, if you wanna do it properly, you need an 2003+ R1 Swing arm, that slots in with some spacers, and the front end of a 1989+ GSXR1100 (17" wheels, upside down forks), you will need the yokes aswell.

Its do-able, but a complete pain in the ass, just stick with the 18" rims

from oldskoolsuzuki.info article

"Handling? 750J rear wheel goes straight in, as will the front end from any of the GSX-R series. The steering bearings are identical on all models, so there's no reason why you shouldn't stick in upside-downers if you like. Best to change them, I think. A 17mm master cylinder (1000 Exup) for the brakes will transform the standard brakes and use SBS-RQ pads for maximum breaking."

One suspects (hopes) that the author means braking.

After reading the entire article, i wouldn't be so sure. The guy seems like a bit of a prat, "Dump any flatslide carburettors that come with your GSXR and replace them with CV carbs, flatslides are guaranteed to break"

But hey, i'm not too fussed. If avons are what people say they are, then they should work like a charm.

Well, great :(

The NZ distributor of avon tires doesn't bring in storms for my rear size :( Great...

Found some other options though, these being dunlop GT502 touring tires (never had any experience with these) or the slightly more expensive option, Pirelli Diablo rear and Diablo Strada front.

Either that or bung on another set of Sports Demons, which i would like to avoid if possible...

Hmm, the stock rear tire size is 150/70x18, I can put on some downright SEXY metzlers if a 160/60x18 will fit onto rim... Will it? Cause that would make my life so much easier

it well fit on the rim, I used to race one back in the eighties, and fitted a 160/60 Michelin on the back as my prefered tyres were out of stock, the only comment I would make is it didn't seem to help with high speed straight line stability. The stanard tyre size on the GSXR750F(1985) was a 140/70.

Thanks for the info :) Looks like Conti road attacks or Avons will be the go, hell, metzler road techs will fit aswell.

(and mine is a japanese import, which came out of the factory with 150/70's as opposed to the 140/70's everywhere else in the world got)
