Funny you mention this. I have same sled and don't think it's much lighter in the rear than my 1200 wasI'll tell ya my 18 MXZ-XRS 850cc is No light weight ! It weighs a Ton ! I think the rear end of the sled is heavier than my 17 Summit 154 X 850 !
1 1/4" standard ripsaw. Was really surprised to see the 25, that was suppose to be for the tall tracks.1.6" ic 129s get the 25t ,1/4" get the 27t gades get 25t with a 1 1/4" and the gade 1.6 ic gets a 23t .BRP doesn't use a 26t because they don't like the dog leg in the chain .The 2016 xrs came with a 25t gear with the 1 1/4" track ,but most geared up .If your one of those that like to over stud you''ll find gearing up and spinning all that weight will kill your top end . :wink_old:
