just measure the actual travel
I have a DL650 with ABS (08) and i have installed Superbrace
I have disassemble the fork to put different springs and emulator in. I measured the travel whilst the bike is jacked up and fork cap and springs out to see if anything would hit.
the following are my observation
1) the actual travel available (taken into account the "negative" travel by weight of wheel acting on top out springs) is approx 143mm or 5.6 inch - i dont know where suzuki hide the last 7mm. measured top out spring travel due to weight of wheel is about 5mm
2) The wiper will hit the triple clamp if you lower by more than about 15mm at some point.
3) because the oil lock out piece in at the bottom of fork, the last 10-20mm of travel is effectively impossible to get to. That probably explains why some people can lower 25mm and get away with it.
4) IF YOU HAVE SUPERBRACE or KB FORKBRACE AND HAS ABS, the brake distribution block / brake hose will hit the superbrace before the fork wiper hits the triple clamp.
5) my solution to 4) above is a) lower by no more than 10mm and b) turn the turn the brake banjo joint anticlockwise by 30 degree for about 2-3mm clearance
6) use a zip tie to measure actual fork travel. If you are not getting to the last 20 mm of measured actual available travel when braking very hard over small bump, then you should change the air gap to allow greater use of available travel. The last 20mm is quite impossible to get to because of the standard oil lock piece and is really whatever shit we havent anticipated that can happen out there!
7) the effective usable travel on everyday ride is only about 117mm (and not 150mm) on the compression side after taking into account the negative travel caused by the top out springs!!!!!
someone may want to chime on this observation
