[QUOTE="cleonard, post: 68064, member: 21"] The horn is the must have track accessory. That way it can be a block pass with a beep, beep... From an emissions standpoint the non FI 2010 version almost met the on road standard. It missed the HC+NOx with a reading of 0.9 when the on road standard was 0.8. You would think that the 2011 FI version will be a little better. All they would need is some upgraded evaporative emissions and it could be a street bike. Well that and an electrical system with signals, stop light, etc. I think that the real reason are the warranty requirements. You see there is a mandated emissions warranty on any street legal vehicle. For motorcycles the minimums are 7500 miles for 50-169cc, 11k miles for 170-279cc and 18k miles for the larger displacement engines. I think this requirement is a big reason the Japanese manufacturers shy away from high performance dual sports. They don't want to be replacing engines because it no longer meets emissions numbers.
