Yeah, we know that straight-cut gears are stronger than Heli-cut, but c'mon really? Is anyone here at risk of crunching 5th gear in their 2010 or newer 6-speeds, other than maybe the 1 or 2 guys here runner a Pro-Charger and nitrous?! We're not building drag bikes here. The likelyhood of anyone destroying 5th, or any other of the other 5 heli-cut
gears in the tranny are slim to none. However, i guarantee someone here has noticed their 5th gear whine excessively in their 2009 bikes (it was all over these forums a couple years ago when the 09's came out. Not to mention all the Moto-mag write-ups).
As for the front wheel? I don't see alot of Dudes putting 17"/16" wheels with fat tires on their baggers. Nor do I see many successful
bike shops selling alot of 17"/16" wheels for the new baggers. Not too many threads here claiming... "Yo Dudes, check-out my new 17" front wheel and matching rotor"!!
As for the header pipe. Even though it's common knowledge that 2-1 is better for performance (ask the Pro-Charger guys)... I'll let you have that one since the oem header is usually
first to the scrap pile... cat or no cat. The 2010 pipe defiantely sucks becuse of the cat-converter. It generates a ton of heat, and restricts flow/performance. Even the 09 has an extremely pinched flow restricted cross-over pipe to the left side muffler. A good header, like the V&H Power Duals is a smooth, large diameter crossover pipe for improved flow.
By-the-way... I wasn't trying to convince anyone the 2010 SG is better than the 2009. My original reply was to simply point out some differences between the 09 and 10 bike that no one else had mentioned yet. Thats what the OP was asking for. Either bike will most certainly due! Whichever one you get though, I just recommend getting it in Vivid Black. "Because everyone knows Vivid Black is faster"!
