Quote from: woodsracer on November 14, 2018, 08:33:04 pmI don't really understand the response about the bike physics though. If the bike is not responding any differently to rebound damping changes across the whole range, is it possible to modify the code to allow a larger range of adjustment? Is there any info on this? Can I find out specifically what fork offsets are accessible for a particular bike by changing from the low end to high end of adjustment (ie. what is the actual offset value on bike when adjustment is set to zero, not +/- anything?) Any way to find out how much trail you have, fork length, wheelbase, etc? Maybe I'm asking for too much.

Quote from: Gibbon on November 15, 2018, 07:11:43 amGreat. It could be very interesting if someday, you can write a post about "Suspension Tuning Basics".Mostly, how each parameters affects the behaviour of the bike and what your experience taught you.Thank you.
Quote from: HornetMaxSpring: this is the spring stiffness, i.e. how much force you have to put in order to change the suspension length by a given length. Units are Newton per millimeter (N/mm). In case somebody cares, for the front fork GPB considers that there are two springs (so the total stiffness is the double of the value you set).Bump and Rebound: these are parameters of the damper, in charge of attenuating the oscillations due to the spring. There are no units (in practice), on a real bike you typically have a rotating dial and you count the number of clicks. Bump acts when the suspension is compressed while Rebound acts when the suspension is extended. A high Bump will make the suspension compress slower compared to a low Bump. A high Rebound will make the suspension extend slower compared to a low Rebound.Preload: typically, the spring is compressed by a given amount even when the suspension is fully extended. The Preload allows you to change that amount and can be useful to avoid the suspension hitting its limits when riding (bottoming out, topping out), as the preload effectively changes the sag (i.e. the difference between the fully extended length of the suspension and the length compressed by the weight of the motorcycle and rider).Front fork also allow to set the Oil level (in millimeters): in the fork you have some oil and some air. The air is compressible and hence acts as a spring, but as a non-linear one: the more you compress it, the more its stiffness increases (in general, this is labelled as "progressive" behavior, while the opposite is "degressive"). This effect depends on the initial volume of air: more oil (so less air) and the effect will be greater (i.e. the stiffness will increase more when you compress the fork). Typically the impact of this is sensible only for large compression of the fork.
