Good post Tom, except Raising Links are shorter than stock and STIFFEN the effective shock spring and dampening rates by decreasing leverage on the shock......opposite of the lowering links.
The problem with just raising the rear is you are going to have a steeper head angle ('cause the '08 forks are 7.8" instead of the Gen1's 9.1"). As you mention, this may not cause a problem, but I'd want the front and rear travel to match fairly closely myself.
- Put in a Gen1 link and matching dogbones and have your Gen2 forks modified to Gen1 travel.....a couple of people have had it done. Best of both worlds; Gen1 travel and the slightly larger Gen2 forks (41mm vs. 39mm). If you go to all this trouble you might as well replace the shock with a decent one (Cogent Moab or Adventure is my recommendation) as well as adding DDC's to the forks) . If you want to know more about extending your Gen2 forks, PM me and I'll give you some contact info from somebody that's done some.
- You could have Cogent build you a shock with longer travel that retains the stock Gen2 linkage.....if you are thinking of a better shock anyways then this saves time + effort. Still have the same front end issues to think about.
- Also up front, the $$$$'s option is to use Emig Racings custom KLR triple clamps and go with KX450F forks.....which should be re-sprung and re-valved to suit the KLR. Honestly, this is cool but has a host of other issues including steering stops, retention of stock gauges, you need the KXF wheel which has a smaller axle, wheel bearings, etc. The Cogent goodies give you 90% of the improvement at 25% of the price and the rest of the KLR isn't up to the capabilities of the KXF forks anyhow......soar like and eagle and land like a grand piano! ;-)
Give Rick or Todd at Cogent a call; they've dealt with this exact scenario many times and are happy to give you their professional opinion with no pressure or bias. Cogent Dynamics - USA Made Motorcycle Suspension
