Why not visit with Peter & Brock at Side Effects in Kamloops. Am sure they could whip up a custom subframe for you in no time. I think that bike would make a nice tug, but with a lighter sidecar... just my opinion. There was a neat little rig for sale in BC Kijiji recently that they'd built - an adventure style sidecar on a Honda Transalp.
Spending my daughter's inheritance one motorcycle at a time.
Bikes currently owned: '91 Honda Gold Wing with sidecar, '92 Kawi KLR650 with Enduro sidecar, and '94 & '97 KLR650s.
