This is the best thing I could have done with the bike, massive bottom end, plenty
of grip, infinitely better suspension and brakes that work even when wet.

There's a few of us heading out to the same place on the 30th and I hope to test it
a little more, but so far so good.

Bravo.

I love mine too. The DRZ forks are huge and beefy. They are a 10x upgrade from the stock.

I agree, makes the bike way more usable. My DRz400 hasn't seen the light of day in more than a week ! :)

Not much apart from 50mm bar risers, the exhaust Y-piece, and the bashplate to protect the y-piece, FD Vent mod, top shock mounting re-location, Battery-box rotation, permanent GPS fitting, Vacuum moulded HPN Tank protector, Kill-switch, front brake light switch, choke lever, double check driveshaft phasing, seal carb vents, time to enjoy it now.

Hi Phil, it was Prutser pointed out the shorter torque arm causes the bottom cup of the shock to impact the swing arm, moving the mount point back gives additional ground clearance combined with more travel. I will cut out the two mounting plates/gussets and weld in two new wider and stronger ones which will allow the top eye to be 50mm further back.
That's the thought, in a nutshell, the shock hits, the back of the bike is too low, etc....

If I'm wrong then 5 minutes will revert it. What d'ya think. ??????

Like the rear shock in this one

with the shortened arm, what happens to the rear joint angle when the shock is in the compressed position. ?

The shorter torque arm causes the FD to pivot down around the pivot bearing, this puts tension or reduces compression on the shock, moving the top mounting point counteracts this. I can't see any real downsides, it's something I can try out and revert if needs be, your photo above is exactly it, is that HPN or BMW ?

Edit: By the way, I've only shortened the torque arm by 10-15mm.

That's one of Matt Beeker's bikes I think - the guy that runs BMWboxersupplies.com aka boxertoko

I think (speculate) that the laser cut strap running down to the bottom subframe mount is also important to brace the extension & to triangulate that area.
