The rear sus is very effective. Its not the 8' of travel you get now on the serious DH rigs, but its enough for most day to day situations and a very capable XC machine that inspires a little more confidence than if riding a hardtail. You can also adjust the rear sus unit on the trail, to run between almost lockout to full floating.
I only asked because I read an MBA article back in 96 where they talked it down as not being very active, and I was interested in getting a "real" opinion (MBA aren't always the most reliable with their reviews). I assumed it must have been alright seeing as they sold in huge numbers and continued to be produced for a few years after the LTS came out (not too mention the fact Sunn Chippie stole the design for its DH bike)!!
