As Six mentioned , I run a 200/55 with 18t / 47t with speedo healer . I am riding in mostly tight corner country , and on occasion , some sweeping corners and short straights . There are places that are more open road , but these are a distance away and north of my preferred rides .
So I like the bike to respond with urgency with any amount of throttle input and in any gear . In tight country , I tend to use 3rd & 4th tooling along and if in a hurry the lower gears to really punch from corner to corner , it gets it done fast , but a better handling short wheelbase bike will possibly be slowed up in actual corner , but pegged back with a suddenly developed reverse gear.... anytime the L2 is back on the throttle . On more open country it really is both corner and straightaway fast , and will now easily pull to top of 6th gear quickly , whereas the standard geared , pre- ecu flash etc. , 6th was definitely an overdrive with my fat ass on board . I got to add that the added 1/4 turn throttle needed to be setup to my personal tastes , because combined with the shorter gearing , can be real sensitive . What really is the absolute icing on the cake for this potent L2 ride , is the slick quick shifter , what an amazing benifit it is to overall acceleration through the gears , really adds to the special feel of this bike . If you are physically heavy , well the shorter gearing and ecu flash ( Gen 2 ) , is great way to liven things up .
