“The other shock is good but the bgm sample I have follows the road better than it.

 The other is slightly overdamped and still skips and jumps on the road even when set up correctly as high speed compression is too harsh.

 The new bgm has gained some really nice mechanical grip with my mods.

 These are the highlights of the new shock:

•   Can be set up quite firm without being harsh for faster engines or 2 up.
•  Rebound control is not just better, but also easier to set up.
•  The damper shaft might be thinner than on other dampers, but this is good because it doesn`t displace as much oil. This means the oil will not overheat and there is more space for more oil. (win-win)
•  Can be used on Series 1 and 2 and Series 3 without compromising on the stroke length.
•  The use of more but thinner shims gives more control and the added bonus of pyramid shim stack is that they are progressive. This means that if you hit a hard square edge you automatically have firmer high-speed compression control. A faster movement on the shock gives more support through-out the shock stroke.
•  We have cured the top-out issue! Yay! No funny noise and better rebound damping.
•  Because of the shim stack configuration, we do not need to use progressive spring rates. This give the illusion that the stroke is longer than it is and although we can use the full stroke, it doesn`t bottom out harshly.
•  I recommend 15-20% sag when setting up the shock, and I also recommend just 2-5 turns on the spring preload. 2 =75kg rider 5 =110kg rider. A spring always behaves better under less preload. I used 3 turns but backed it down to 2.5 (82kg with gear) I also have rebound set at 14 clicks from fully open.
