I think a stock '01 and '02 will do 186 top (governed). I have had my '01 to 170, and it had some pull left... My buddy said he hit 180, but then again I don't know if I really believe him... I know at 170 my head was whipping around so fast I could hardly see anything at all, let alone the speedo..........
Depends on what you call stock. No engine work is stock and will get you well over 180mph. Pipes etc. will get you over 190mph depending on your weight. I have hit 189mph on the GPS and expecdt to hit 201mph once the winds die down.
This speed topic was covered in the magazine "Sport Rider" October 2001 titled "No Limits--We Derestrict the Hayabusa and ZX-12R. Actually it is a series of articles.
The article found the stock Busa was 158.0 HP at 9750 and 98.4 at 7000. It is limited to 300 kph or 186.7 mph Using radar guns on stock bike, they posted 183.9 mph for the Busa and 185.6 for the ZX-12R. Using the TRE or equivalent they got 192.4 mph for the Busa and 190.2 for the ZX-12R with a slight tail wind. They did other runs under slightly conditions and modifications to both bikes and the ZX-12R was slightly faster.
Hope I got everything right, but you can read the article.
OK this may sound dumb but how do you use a GPS to tell speed I dont have one is there a button that does it or alot of math My friend has a radar gun and I was going to use that and see what my busa would do I know with just a pipe on my 2000 I can smoke him on his 900 Kawi and he said he ran 170 on radar I was only in 5th
I think maybe on a cooler day I might get to 210 we will have to see though. I would have to change gearing to go faster as stock busa is geared for 207 so I think gearing is the limiting factor right now.................
Wow..no wonder it goes so good..125 hp's at a ridiculous low rpm of 3,500..amazing..and then close to 150 hp's at 6000...rode near sea level last friday..had a hard time believing how the busa just lunges ahead at those low rev's..third gear....guess you can't just twist it up anywhere anytime..pavement better be smooth....learning..makes a veteran sportbike rider feel like a newbie..which is good....what a mental challenge....scaryfun..
Ya reading the lines incorrectly, the 125 at 3500 rpm is the torque curve and the other is the HP. But that much torque so early does make the the bike kick from those revs quite nicely and the surge of power after 7000 is the HP. Thats why for standard street riding i hardly have to go above 4000 rpm unless i wana have fun.
