The LB is very similar to trials bike suspension and handling wise in stock form(after properly servicing them and adding oil, at least on the RST I had), the brakes are the biggest drawback out the box imho. I only recently came up with the brake solution of running the formula brakes from cake kalk/ktm 65s both front and rear and there have been plenty of solutions for the LB on forks and shocks(kx100/85 and yz85 forks bolt right up with a little grinding, gritshift has ktm 85 conversion and I make conversion for 65s that also works for 85s). I have less than $1.5k into my suspension and brakes so its not that bad to get a good setup now.
But back to the main topic, the UB has everything done the way it should be other than arguably the wheels but even then several seem to be happy with the 19/19 combo for average trail riding which is nice for range. Forks and shocks are at least going to be competitive with gas bikes in same category(crf250f, klx300r, ttr230, etc) and they fixed the brake issue on the LB with actual moto brakes. Basically its just a better version of what I built out of my LB when I was targeting completing the TKO which I did and now selling to move to UB.
