Hi, I've searched for the answer to this but am still confused..!! I want to fit a fatbars/triple clamp setup to my '04 WRF450 and was all set to order a Pro Taper adjustable one for an '03 YZF450 from rocky mountain, but they tell me that it won't fit my bike. I'm aware that some mods to the odo bracketry will be needed. I'm pretty sure that it will fit from what I've read on here, but can anyone who's actually done it confirm for sure ? Also, rocky mountain list a Longhorn clamp for an 04-05 WR450, but I thought the forks were different sizes between the 04 & 05 models, maybe the outer assembly tube is the same OD?? Any one have experience of the quality of 'Longhorn' brand?? Any help greatly appreciated as I'm ordering from the UK & don't want to get something I can't use!
