thats a bone stock 900rr runnin 10.5....mine isnt bone stock...I made tat run with a streched swingarm, and strapped front end, two thing that the riders in your numbers didnt have, also a fullexhaust ( which I ran uncapped )and filter, and with these factors Im sure that thats more than enough to account for the 10.4 instead of a 10.5 i dont need a slip, you just need common sense

 

I saw a kid run a 10.7 on an o6 gixxer 600 STOCK...go to http://islandracer.com/and youll see some of the stuff we play with over here.

 

I outran this one busa numerous times one night..........oh but let me mention....... I bet the guy outweighed the bike by a few and was about 6'8". Couldnt ride either. This was before I stretched mine. I dont get to race but maybe once every month or two. I just enjoy running for the hell of it and seeing people in disbelief when I run mid to low 10's on a 600. Most people dont realize the pontential of the new bikes....600's and 1000's. I laughed at a guy running a worked over and looong zx14 bragging about 9.2-9.3.... I know a guy that the first time he took his stretched and worked zx10 and ran 9.26 his first night running.
