Me too, I would like to get rid of the Tractor Grip, IRC's on my Z50r. Curious to see what others are using on 8in rims.

I have a '71 too. For years I had a 4.00 x 8 IRC trials tire on the front and a 4.00 x 8 Nanco tiller tire on the back, with tractor tread, so I could ride in mud and snow too. It worked but rolling resistance was high and the ride was harsh.

This year I moved the trials tire to the rear and run lower pressure in it to soften the ride--major improvement in ride smoothness and decent improvement in acceleration and top speed on pavement--and now I have a Michelin S83 scooter tire, 3.50 x 8, on the front. For all-around street riding on a Z50 I'd give the Michelin high marks. It's smooth and feels secure. I'd consider running one on both ends except for the fact that it totally sucks in the mud.

I ordered the Michelin through my local shop's Tucker-Rocky catalog and I think it cost about $30, and I believe it's got a "J" speed rating (62 mph). Not sure, but I think so. There's no 4.00 x 8 version of it that I know of but I think it does come in 4.00 x 10.

I have a set of KINGS they are 4.00 x 8 street tires that i'll probably sell after sunday. They aren't made anymore and are super hard to find i guess.

Heidenau K75's. Either 3.5X8 and 4.00X8's. Best 8" supermoto tire available stateside.

let me kno if your sellin them

sketchycheck

where you order them from

moto234

he can order them for you. he had a few a couple weeks ago but probably sold them now

sketchycheck

and hey do you guys kno if i can put newer crf front suspension on my 71 frame ?

50minikid

you can use the lower fork legs, springs etc but not the upper gold part because it is too narrow for the z wheel

sketchycheck

ahh alright i put my z threw hell before i got my race bike and my front wheel and fork legs moves forwards and backwards like 3 inches you think think its the forks itself or the legs????

mexicanyella

It's either the bushings inside the upper section or your steering head bearings are really loose/trashed. Is the movement confined to just the wheel and lower fork legs?

50minikid

most likley bushings, you can replace with some HD bushings and you might want to use some stiff springs so that you don't bottom out as much

sketchycheck

ya i just checked its just the fork legs and front wheel that moves. you think that the new crf legs and bushings will stop that or do i need hd bushings??

mexicanyella

Stock replacement bushings will stop that, maybe not for as long as HD ones. Do you know how to replace the bushings? Have you had the fork legs out of the uppers to verify they're still straight?

While you're thrashing the front end like that, what's going on at the back? Is your rear wheel still held on by a straight axle? Man, with mine the front end is the least of my concerns.

sketchycheck

and its only gonna be a stunting/motard bike no more jumping its getting completley redone so no need for stiff springs

sketchycheck

its a hard tail and i actually cracked one of my hubs in half off a hard landing.and i bent 2 axels hahah and ya i have had the forks apart many times im on my third front end hahah

50minikid

I found the hd bushing from companies like red baron wern't much more than OEM ones from honda.

Anyone ever try the Bridgestone Hoops? They look nice. Only 3in wide, rim calls for a 3.5in. Will that work or will they be too skinny?
