The more ballerina size slippers are nicer and easier to ride around on in lightness of control and throttle response but wear factor definitely goes up as size goes down. Its a fairly subtle difference that takes some extra throttle and flings to sense though. I've only this year tried a 100 on front instead of 110 and now wondering if I've hurt my braking ability. I was swayed by the almost universal reports of most fitting 100 front and 110 rear. The most practical sizes for my varied on/off road conditions for wear and security was 110 front 120 rear. Traditionalist who depended on their Commandos for daily transport fitted same size front and rear and rotated old front tire to rear with new on front. But shoot its like hair cuts, only lasts so long so can try various sizes till sense of tire preference soaks in. This is another reason to call world wide list of vendors to ask what they sell most or recommend plus price shop. Factory disc brake ain't got a lot of power to squeal or lock front tire, until the factory restriction opened up, then may notice tire noise to worry ya on front size choice.

I use 100/90 AM26 Avons on both front and back. When the rear wears out I switch the front to the back and put the new tire on the front.
You just buy one tire then.

The 100/90 does'nt really fit the wm2 rim properly, it goes on but pulls the edges over,I haven't tried it but you may be better fitting 90/90 front and rear
 
I am sure that there are literally thousands of 100/90 avon on stock wm2 rim and the only issue they have is why they didn't get them sooner. I had no issues with my Roadriders on stock rims.

WM-4 mate! give a pm to fullauto and get his input on am26 with tires. I went WM-4 and love it
took his advice and never regret. he makes a nice commando head as well.
Cheers ,
CNN :P
 
I remember that tire thread from a little while back and will probably go with the WM-4 when I get the cash, glad to hear a second endorsement on Fullauto's wheel set up. Also there's a lot to be said for swapping the front to the rear and mounting the new rubber on the front. Cj

Doesn't mean it's correct though does it

No splatt, you are right. They are not correct.

Attention! All those with Roadriders om wm2 wheels please take them off now. NOT because they don't work but because splatt says that they simply are not correct. Also, if there is anything else is on your bikes that are not correct (iphone mounts) you better get off or the correct police will get ya.

Just curious, all those who have had issues with the 100/90 roadrider on wm2 rims, please let us know so we can help deny ying the benefits we all enjoy.

Good choice. If you check with the tire manufactures rim size recommendations, you'll see the WM-3 is a bit on the narrow side for most rear tire selections. I'm not debating the performance of WM-3s, just pointing out tire manufactures recommendations.

I run a 120/90-18 with a WM-4. Very happy.

We arent denying ying (!) anything .
Not only is a 100/90 on a WM2 not correct , but it is plain stupid .
Why ?
Because the cheaper alternative of a 90/90 tire front is a far better solution and readily available .
Fair enough! Thanks ludwig.

You should really stop running your mouth and and go and see what a 100/90 roadrider profile looks like on the correct size rim, the peaky middle and pulled over edges dissappear
 
Why so ctiticle. I have enjoyed these tires on my wm2's for 2 years. They operated fantastic and ran rather true even though I had a bad offset. No wobble, no shake. I now run shouldered alloy wm3's and although they look so much better I don't really feel the differance at 45 nor 105mph.

We're talking less than 4mm a side here. He will save whopping $1.00 per tire if he goes with the 90/90. If he goes with a 100/90 and desides to upgrade his rims next winter, he will be good to go. That what i did.

"Correct" is relative. This situation maybe a little out of spec, but not incorrect IMHO.
I do run my mouth through experience.
 
Hi Guys, just been reading the thread, i have std rims VM2's I am running an Avon Venom 100/90 on the front and a Dunlop TT 100 4.10 x 19 on the rear.
I need a new rear and was looking at replacing it with another TT, if I switch my 100/90 to the rear and put a new 90/90 on the front i know it will steer quicker.
So what are your guys thoughts on this, I don't have weave or wobble issues, hands off the bars no problem if , although does pull to the left slightly, nature of the road cambers here in NZ. Push the bike pretty hard on our twisty roads, so far no issues.
Feed back appreciated
Regards Mike
