I've owned the Hyper for about 6 weeks now. Saturday I changed the front sprocket to a 16th (+1 from stock for those that don't know) and really noticed no major change in power per say. Although at cruising speeds I dropped the RPM's down almost 1k rpm. I made a mental note of the RPM's before the swap. Due to the low gear ratios of the transmission, 1-3rd gear are non-issues power wise. 4-6th are a bit taller feeling for sure. I can still easily wheelie in 2nd and 3rd is a bit more challenging than before.
My overall thoughts are this was a good move for me. I did 320 miles yesterday and this allowed for a bit more range on fuel. I can easily get 110 miles before the fuel light, if I ride semi conservatively. If I twist the throttle a lot, which I did yesterday hitting 130mph multiple times, I got the fuel light at 90 miles.
I was considering moving the rear sprocket down 1 as well, But for now, I'm gonna leave it be.
So far the Hyper is my favorite all time bike. I've had a bunch over the past 18 years. I'm a road race junkie and actually run the video bike program at our local track. So my normal rides are liter bikes (Kawasaki). Here is a pic of my tard 6 days after I picked her up! And a pic of my current race bike...
It's been a weird thing moving to this style of machine, as I've ridden sport bikes since I was 18. I gotta say though, I was getting burned out on street riding and now, this has gotten me back into riding the streets again. I was nearly at the point of track only... Although I plan to take the Hyper to the track again, I prefer to NOT crash this bike!
