on a 162 probably worth it. All the 2010's are geared 55/65 now. If your changing I would probably buy your 57/63 gears off you for my crossfire. If shipping isn't out of hand. PM me if your interested.
Buddy of mine geared his 153 down to 54/66 last season, and it worked awesome for him. His belt heat issue cooled down, and just seemed to work well in all our conditions. Ill be picking up a set before riding season for sure!
