Having any year RC is good, each has its differences.
The SP2 was modified with a slightly different rear suspension setup, swing arm, throttle bodies (or injectors) and a few other minor things (oil cooler moved, bolts moved, etc...).
SP2 was rated to have a few extra ponies and a few less pounds.
RC is an RC...so enjoy the love as many of us have.
