Well that depends on where u r racing what type of terrain . Your machine is a WHOLE lot lighter that his but his has a lot more horses. That machine will also corner a lot better than u think polaris designed that machine using what they have learned from there sport quads. Im gonna say its pretty low geared. So In my opinion 549cc campared to around 200cc give or take a few u r out motored, but u have the weight advantage big time. I wouls say if u race him on a straigh away u would prolly pull away from him quickly. Your best bet would prolly be a tight trail with hard ground. Thats just my opinion.
