1. I believe there is a basic design fault with the wheel design.
2. It is a spoked wheel where the only adjustment / tension check requires access from INSIDE the hub Fault#1
3. In a spoked motorcycle wheel the rim edge is meant to flex when a rock/hole is hit. The rim 'deflects' elastically to absorb impact. This movement is why spoke tentions need to be checked.
4. In an e-type jag wheel the spoke can be checked, but the lacing design is intended to keep the rim FLAT on the surface. Unlike the requirement for a motorcycle. Fault#2
5. Spoked wheels are meant to 'twist & deflect" vs a "mag/cast" wheel. This meant the design is INCORRECT for a motorcycle ADVERTISED as going 'off-road' / 'bitumen' Fault#3
6. A canterstand can be fitted to V85TT, but it will not support bike if front wheel needs to be removed. Secondary issue.
7. No breather / vent on rear axle houseing and sudden changes in temps (creek crossing?) can cause a fail on a seal that seems to be holding back air pressure and +/- 20ml of oil can cause a catastrofic failure. Potential loss life on an "adventure" bike. Secondary issue.
I'm laying these thoughts out here, as I saw one guys pics of a "wheel-fail", looked like 1 spoke broke (tension wrong?) and rest of wheel failed. I suspect the above design flaws are such that a RECALL be issued for the wheel design.
As a possible solution I would point to Montessa 4RT rims & spoke design. Tubless & With rim locks will go 4psi which could help in sandy / bull dust areas/holes/bogs etc.
So yes I think a recall is required, but I'm also trying help MG with some design ideas to build a better "Desert Sled" (Aussie only model? No EU regs here - yet!)
Please post comments, interested in thoughts before posting in V85 specific forum. (or maybe shoulb be there?)
