Well the TL had the 750's on there and it rode really nice - haven't been out on it with the Kayabas yet.
The biggest noticeable difference is under extreme braking (like emergency stop!) - with the Kayabas, if they bottom out, there is a hydraulic lock region at the
very bottom - so you get a chatter under that condition as there is no-where for fluid to go. There is a relatively simple mod you can do to relieve that but I hadn't executed it.
For general performance the Showa just has the edge in better feel for me (and a change in aesthetics, to be honest).
But can't go wrong with either one - as OEM equipment both are excellent performers.
The TL is probably going up for sale soon, so thought I would keep the Showas, hence the switch
The Kayabas off the GSXR 1K still a much better prospect than the OEM Triumph Showas!

(and probably also better than the TL's earlier generation KYB)
Have to say it was fun juggling two bikes in the air swapping front ends around!
Here's a less glam shot of the TL in the garage just after the conclusion of the swap.
