Hey now... having the same has it's benefits. With 2 250's and 2 r6's, I have options for real fun with friends.
I can loan a bike to a friend for street or track ride (yes, I have loaned for both
)
I can button one up for street and the other for track
I have a spare to take a part/tire until a new one comes in
There are positives, it just depends on your use and riding desires.
