250-500cc WR300 vs 300xc

2 of my buddies are KTM Canada Factory riders and they both pull the e-start of their 09 250XCs. They both claim the extra weight on the crank makes the bikes feel a lot slower than their 08s without the starter.

Still hoping Husky decides to put them on their bikes. Can't say I've compared the same bike with/without the starter, but sure, if I were a Factory rider, I'd be looking for any/every advantage so that makes perfect sense. For Joe Schmoe's like myself who are out trail riding every weekend, the E-Starts a HUGE selling feature. I'm just sayin...
