Beta offers a lowering kit in increments of 1" and 2". I would go that route before messing with the linkage. The linkage will effect the geometry of the bike. I'm not sure the suspension kit effects the geometry, but it will have less travel.
I appreciate the video and got a lot out of it. I do wish when people do videos like this that they add some basic information so people can relate, or even a before and after... For example, what is the original seat height, what is the final seat height (granted you should be able to do this with the spec of the bike and seat concepts info). Then, what is the INSEAM height of the rider???? Ideally, we would have that, show her getting on the bike BEFORE with the original seat and then the AFTER with the Seat Concepts seat. For shorter riders, there are a number of factors like slimness of the bike, the typical sag, etc. When someone says they are a certain height, you have to keep in mind that the height above the ass doesn't matter, it is the INSEAM. Anyway, I appreciate the video just the same there was a lot of good info and worth my time. :)
I'm 5'5" , 28 inch inseam (no shoes). I have a 2017 Xtrainer 300. The original bike is too tall for me, no dab, no one foot, just too tall. I have the Seat Concepts low OE width (not the comfort low seat - it is WIDER). The Seat Concepts low seat is only 3/4" lower than stock at the lowest point. I have also had my shock lowered 2 inches internally (Delrin spacer), which also removes 2 inches of travel ( from 10.6 to 8.6 actual). Plus added a shock spring suitable for my weight and the reduced stravel (higher spring rate). I have also raised the fork in the triples to max (30mm) I have the original fork travel there, I need it to hit obstacles. This somewhat balances the geometry closer to stock. Overall my Xtrainer seat is about 2 inches lower than stock. I've been playing with the idea of modifying the subframe somehow to lower the seat height further, and maybe even making my own seat pan from ABS and heat gun, minimal padding like a trials seat. I wear padded bike shorts anyway. Anyway do whatever you can to make a bike comfortable/safe enough that you could easily dab in hard terrain. Getting both balls of the feet on the ground on a lever surface is ideal.
