Well, I think Im going to take the plunge and step off the WR250R, and buy a WR450F. I just havent been convinced the WRR was the right bike for me. I dont ride on the street anyway. I ride single track trails only. So I want to know if 6770 OTD is a decent price for an 09 WR450F. I think it sounds fair, but thought some of you might have some input. I really hope this is the right move. I am a bit concerned about the power difference in the two bikes, and the long day on the trails with potential vibration on the WR450. Im fairly new to dirt biking, so I just dont want a bike that has unpredictable power that may "suprise" me. I know the WRR has no vibration and is comfortable to ride. My issue with the WRR is the general lack of power, and the EFI on the trails causes some throttle jerkyness I dont like. Ive always been partial to EFI, but not sure I like it on a trails bike. Anyway, thanks for any info. I just dont want to spend this much more money and not be happy with the bike.
