I had a 130 on the '78 Z1-R and currently have a 140 on the MKII with no problems, even with stock swingarms. Both bikes have the 2.15 rear rim. I think the 130 is much better though according to most rim/tire selection guides. The 2.15 really shouldn't have anything more than a 110, so 140 is really pushing it. I think the stock size was a 4.00 which converts to a measly 101mm! The LTD models at least got a 3" wide rim.

The Kaw List:
Current: 79 KZ1000 A3 MKII, 78 KZ1000 A2, 78 KZ1000 Z1-R, 78 KZ650 SR, 80 KE175
Former: 03 KLX400SR, 99 ZRX1000, 82 KZ750 LTD, 80 KZ1000 A4 MKII, 80 KZ1000 LTD, 78 KZ1000 A2, 74 H-2 750 Triple, 78 KL250

FZR 600 swingarm on 78 Z1-R 01 Apr 2006 20:57 #36071

Just in case anybody feels "creative" ... I put a 1994 Yamaha FZR 600 swingarm, rim and brakes on my Z1-R. It was a mono-shock setup but, with a little welding and a few other modifications it fits really nice and provides a wider rim. The weight reduction is also notable as well, I lost about 15lbs. The brakes, rim and swingarm are much lighter. It's a "bit of a job" but works well. I have a picture of the bike in "The Gallery"
