I had to take my 07 151 in on Friday for some updates.Well with all the reading and vids Ive seen as well as the beer I drank the other day...I made the leap to the XP Everest 151. Soon as I get it back will let you guys know what I think of it. My 07 Rev is running nice though,no probs for 1000 kms.Still has the origanal belt on it....I was in a beer fog and seduced....Cheers
