I've read some discussion as to whether there is a top speed limiter on the 109 besides the 7200 rpm rev limiter. So I went out today to find out...the answer is definitely YES. The ECU limites rpm to 6200 in top gear. What this means is the bike has the exact same top speed in 4th and 5th gear. That is 128mph on a GPS or about 141mph on the inaccurate speedometer. In top gear the bike has a lot more to give when it runs square into the limiter. From the way its still pulling and looking at the horspower peak graphs I would guess the bike will pull close to 140mph actual once derestricted...that would be about 6800rpm in top gear. I dont think it will go any faster stock as this is where peak horsepower starts to decline and the 109 has all of the aerodynamics of a flying brick . I do think it will get comfortably into the 135-140 range derestricted based on how strong the bike pulls into the 6200rpm top limiter. I also did some other testing. Did several quarter mile runs(I can only do trap speeds with my GPS so sorry no times). The slowest trap was 110mph...the best 114mph so I'm very comfortable this bike will run high 11s :bigthumbsup: As for roll ons(top gear), I do 200 yard rolls from 50 mph(GPS). I consistently hit 82mph trap(GPS). That is a GREAT number for a cruiser. By comparison my stock VTX ran 75, modified meanstreak ran 77, and ,well, pipe and pc Hayabusa...91mph. So its not a Busa but what is(dont say ZX14). All in all I'm very impressed with the performance .The 109 is sneaky fast...I really didnt think it felt as fast as the numbers show.
