In the interest of sharing info with my fellow TR650 brothers and sisters, I figured I share my experience lowering my TR650 Strada with both the 1" and 1 3/4" Kouba Links.
First, I'm a bit on the short side at 5' 7" with a 29" inseam. I weigh 225 lbs. I'm big-boned, dammit!
With the OEM link and at the standard sag setting (from the dealer), I'm on my tip-toes (both sides) when sitting on my Strada.
Without messing with the sag setting, the 1" Kouba Link (with forks raised 3/4" - the max recommended by Norm Kouba) drops me down to barely the balls of my feet (both sides). This probably would be a good dual-sport setting but since my bike will be ridden 95% on pavement, I wanted to lower it even further for better stability when stopped.
So, I ordered the 1 3/4" lowering link and with the forks still raised 3/4" (not changed since I installed the 1" link) and sag not adjusted, it lowered me just beyond the balls of my feet. For street riding, this is perfect for me. The bike is now low enough such that I have no issues straddling it when stopped. I would estimate that the bike still has more than enough clearance and suspension travel for riding on forest service roads. The back end hasn't bottomed out yet during my street riding, even with my weight. I am planning on adjusting sag to increase stiffness since I think the back end is now a bit too soft. I expect to lose a small amount of lowering by adjusting sag to a stiffer setting but I think the seat height will still be good for me.
One issue that I ran into (not unexpected) is that with the 1 3/4" lowering link, with the side stand down the bike now sits a bit too close to vertical for my comfort. I am planning on having a local shop shorten the side stand to bring the bike back to its OEM lean. With the 1" link, I felt the bike lean was still in the "safe" zone with the unshortened side stand.
Anyway, that's been my experience lowering my TR with both of the available Kouba Links. Regarding the links themselves, they are the usual high-quality pieces that Kouba is known for. I have no complaints and they work as advertised.
Also, for normal street riding, I experienced no adverse effects with the Kouba links installed. The bike handled and steered just fine with either Kouba link installed. I certainly don't ride on the edge so I have no data on how they affect steering and handling at the limit or off-road.
Hope this helps!
