Brent, I love your work, especially on the lower backbone around the relocated swingarm pivot. Very clever use of that small 'gap' in the rear of the engine cases.
Just wondering though if there's a reason you're not taking the opportunity to reduce the wheelbase somewhat given how long the RL is (53.5"/1345mm) compared to all other twinshocks. Just curious.
I do like the RLs even with all their faults. I enjoyed sampling Greg's Squeamish alongside a standard RL at his place a couple of years ago and it made the standard one feel very ordinary by comparison, to put it mildly.
Another one I sampled had minimal mods: 360mm Rockshocks, forks dropped through the triples as far as we could (which is only maybe 15mm as I recall), and footpegs lowered & moved
forward as far as possible (which amounted to about 20mm ea way) while still allowing clearance for full kickstarter swing. I thought the steering might have tucked under more with even less trail, but try as we did on some practice ground we couldn't feel any. Admittedly there were no sizeable rocks, logs, sand or steep drops. It too felt a considerable improvment over a standard RL.
This is not it, but I always thought this one, with its subtle changes, looked in better proportion than a standard RL too

But I could never understand why Suzuki manufactured the RL with that obvious design flaw in the gussets on the rear uprights; ie minimal overlap of the two gussets on thin-wall tubing creating the stress concentration point causing the inevitable fractures. Even more that they never fixed it.
Bultaco notably used a single continuous gusset there.
Have often thought they would have been much better served running that bracing tube from above the rear engine mount downwards to the lower gusset for the swingarm pivot instead of going upwards to 'nowhere' (ie nowhere significant)

And Greg, I'm intrigued by what Squeamish 2 might be. How diff to #1 ??
You both may just have whet my appetite to get back in the shed on one or two trials projects.
(Been given to other projects lately)
I just wish I had half the fabrication talent of you two guys!
