Re: Penske vs. Stock
For most the best money is usually spent on rider(gear & training, tracktime, practice) then bike(tires then suspension then brakes then engine/trans). Even if you only ride on the street you will massively appreciate suspension work - most important is right springs for your weight and use (smooth track vs road with passenger, oem is typically designed for 140lb rider, no passenger), then rear shock (Ohlins $800-1200, get deals on EBay), then front fork internals(TraxxionDynamics, RaceTech, Ohlins for $1000-1200 installed w/ springs). And get it setup right - sag, preload, fork travel indicator to detect bottoming. Then brakes - first front mastercylinder(Brembo $300+/-), then front calipers&pads(Brembo $1200), then front rotors($600+), lastly rear (stock rear is usually fine unless you use it aggressively for wheelie control).
