I don't know if anyone in interested as to what a rear shock internals look like but I happened to come across a knackered DL1000 shock foc, so being an inquisitive type, I thought I'd take a peek...
Stripped and laid bare:
40mm piston with compression & rebound shims:
Blimey, there's some selection of shims....:
The main thing that sets the 1k shock off from the 650 variant is the 1k's internal piston, keeping the oil & pressurised gas separate, note the tell-tale ring of indents around the shock body.
It always surprises me at the attention to detail and construction of what are generally considered low quality items.
