Bevel box / propshaft. The way they line up

Hi Guys,
This one isn't mine, I was doing it up for a friend. I noticed that the bevel box and propshaft remain in line with each other regardless of whether the bike is on its stand or had someone on board. On mine, they only line up when the wheels are off the deck, the rest of the time the bevel box remains parallel with the ground and the propshaft does the moving about - exactly as you would expect.
I took this one out and had no problems so I let them know as I didn't have the time to do more. Aside from a seized UJ which I would expect to feel while riding it (which was not the case) any ideas?

Some models have a slightly shorter paralever strut (lower arm) which does this and slightly raises the rear end, and reportedly gives faster steering. Nothing to worry about.

Nope, standard strut fitted. I'll have to have a dig around next time she comes up here on it. Although it doesn't effect the handling at all it worries me.

Looks like a Nitron rear shock and possibly BCR paralever strut.

Standard strut gives the "crank" in the paralever joint.
Shorter GS or BCR strut gives the "in line" geometry and does speed up the turn in by raising the rear.
Has the added benefit of keeping the rocker covers off the deck a bit longer when leant over "making progress".

Ok thanks, but strut looks identical to mine. I was under the impression that the shorter struts did not look like origional equipment. I'll check it by length next time I see it.

The way that the bike is parked in this picture (on a slope with the front wheel higher than the rear) would tend to straighten out the "Crank" as it is (I would say) leaning over further causing the joint to straighten out. Just stating the obvious here :oops:

GS strut looks the same ,only the length is different.
