Wider Rear Tire

[Douglas]

Unless you want a really ill-handling bike or you just want to go fast for 1/4 mile straight, you probably should not exceed a 160 in the rear on a conventional chassis geometry CBX

This thread reminds me of hundreds of similar discussions over on Miata Forum over the past 10 or 12 years Mike

Take my word for it, there's a segment of the population who doesn't give a darn if it's even safe to move in a straight line - They're going for a certain 'look' and when they get it, they'll figure out some way to ride it . . . . and then likely they'll be back here posting about how much better it handles than a stocker

hey-Hey!!!,
I don't think it'll take more than what will comfortably fit onto the stock rims to drag the hard bits into the pavement. That said... I went up to 3.5 x 18 so I could mount a 140/70-18 K591 on my '82. Worked well enough Mark did the same thing to his '79. Wish I could have found a matching three spoke for the front for the same sort of green. Turned out the greatest benefit came from the lighter VFR wheel, not its greater width and tire choice.
cheers,
Douglas

Yes, we should be road testing the ZRX 1200 w/240 arm tommorrow. It looks sweet! I've seen the stock Kawi arm used on the CBX before so our arm should be quite adaptable to the CBX. Rick

You mean like this one? I did a ZRX conversion 4 years ago and I run a 160 on it, 180 would be the largest tire I would use on my 79 CBX and that would only be after the frame was reinforced and at least the 39mm 81/82 forks were fitted.

It is far from a direct bolt on, it takes a custom spacer, sleeve for the swingarm mounting bolt, machining, welding and shock mounts.

Mike, was it you that called the shop today (Roaring Toyz)? Someone called from PA asking about a custom 240 arm today. Yes, we should be road testing the ZRX 1200 w/240 arm tommorrow.

Rick,
If you can divulge, how are they handling the wider width of the shock mount on the ZRX s/arm to the more narrow width of the CBX upper shock mount.
I am intrested in this swap but with a reasonable rim size.
Thanks for any info.

Guys, I started this thing, and its done very well without me.

I must confess that I've done nothing yet regarding the recommendations.

I do appreciate all the input and will start to assemble the needed stock soon.

(1) In the mean time, I've accomplished major work inside the house (114 year old house's are a challenge)

(2) Replaced most of the hoses and fluid tubing on a pair of Cummins Diesels V8's in my 47 foot Wooden Flushdeck Motoryacht

(3) Added a 2000 Ducati 748 to the fleet, and doing several upgrades to it including open clutch and fairing refinish.

I hope to post several photo's on the sight soon and do appreciate all the help and tips thus far.

Thanks, and Happy New Year to ALL.

Later, George in Delaware

Has anyone ever tried, or heard of anyone fitting a Gsxr swingarm to a Pro-link?
Just wondering if it would fit, so maybe a 160 or 180 tyre could be fitted

A lengthy thread but Mike used a GSXR swingarm.
