Hello all. I have been checking out the forum for a month or so cool place! I have been on two wheels my whole life, mostly all in the dirt. From motocross and harescrambles/enduros to flattracking(which is what I mostly do now)! to street bikes. I have always liked the rc51 since it's inception, and am ready to pull the trigger on a bike, but I would like some input on which bike sp1 or sp2 to go with. I definitley am going to set it up for track days, as Beaverrun motorsports complex is less than an hour from me, and racing is just in my blood! there seems to be about a $1000-2000 difference in prices between the models any input would be greatly appreciated. Thanks!
