Morning Gents

I have a 1989 Tengai with some cosmetic and functional mods including a YSS rear shock, which has made a huge difference from the old, rather tired, rear shock. I was looking at the Cogent front fork upgrade package but wanted to check with Cogent whether they would work on my Tengai. Long story short, they've had varying responses from owners and can't be definitive. They'd also like to know :) so I said I'd come to the oracles and ask

I'm sure the OD of the Tengai forks is wider, but if the ID is the same then potentially the Cogent internals will work fine. If not, then I'm out of luck.

Has anyone installed the Cogent kit on a 1989 B model ? If not, is there a reference on the fork metrics. My service manaul doesn't have the measurements. The references I can see say 38mm for all the Gen 1 and Model B.

Thanks in advance for any pointers.

Yes the rear shock is shorter too! But aside of that you can put an A shock on a B that make it a bit taller!
I wonder if the Cogent short shock for short legged owners of the 'A' model is the same length as an oem 'B' model Tengai shock?

Possibly another example of Kawasaki doing it first & others simply following.

Interesting. The reason I asked is...I have used 1-1/2" lowering links on all my Gen 1 KLR's (with forks slid up an appropriate amount in the triples). And I use a shortened side stand. But with the same links installed on the Tengai the bike does not seem to lean far enough when parked. A shorter shock would explain this. I have never found any dimension information for the shocks so I've never been able to confirm a difference between the A and B models (only that the part numbers are different, if I recall). I guess I should shorten the side stand, not sure how much though.

Put a 1(actually 3/4")x 4 piece of wood under the rear tire, does it lean enough? No.
Try a 2 x 4 (actually 1&1/2") is that too much lean angle? If so split the difference.
