OK WTF? Sport Rider has the new R1 figure at 158 hp at th etire, which seems accurate enough. But 152 for a stock Gixer? BS. Im reading the new performance bikes and they're 03 gixer has 151 with mods, 142 stock. They also had 5 lb/ft of torque less than SR has quoted. It'll be fun to come across one and have a go.

:2bitchsla Dont you know that if in fact the Gixxer for some reason has to be :bs then of course your precious R1 should also be :bs ! It is the way of the mags, to hype up a bike because you do know that most of the time the ones they test are not in fact off the floor but indeed given to them by the manufacturers.:thumbup

Dynos are useful tools for tuning a bike, when you can make a change, run the bike again on the same dyno, and compare the results.

Although I'm sure the dyno manufacturers would have us believe otherwise, the numbers they produce are pretty meaningless in an absolute sense. It certainly doesn't make any sense to compare runs taken on differnt dynos, and it's even highly suspect to compare results from the same dyno that weren't taken on the same day (with the same temperature, relative humidity, etc.). This is basically what SR is doing, and they should know better.

There are lies, damn lies, and dyno numbers.

Hm, there are dynos that get closer to reality than others. But you have to know what dyno was used. If it was an inertia drum -> forget the figures, meaningless.
If it was a brake dyno and all the bikes were tested under the same conditions WITHOUT fan -> may give some comparison but still expect +/- 5% fault, as claimed by the manufacturers (what is ridiculous for equipment that is used to measure)

It does seem tha thier dyno is reading a little high.It is also not a dynojet that most are familair with.It's a factory dyno.Just so you know,at daytona the fusa/ccs switched froma dynojet to a factory and lowered the hp for the hp restricted class's.

From raodracingworld.com
F-USA officials have adjusted the horsepower limits for machines in the Formula Sportbike (750cc Superstock) and Sportbike (600cc Superstock) classes to suit the change from a Dynojet dyno to a Factory Pro Tuning dyno.

The Dynojet number for Formula Sportbike was 145 and the Factory Pro Tuning number is 122.

The Dynojet number for Sportbike was 115 and the Factory Pro Tuning number is 100.

The Thunderbike class pounds-per-horsepower limit has been revised from 3.8 to 4.0 horsepower per pound.

Factory Pro Tuning dynos read lower than Dynojet dynos. Factory Pro Tuning owner Marc Salvisberg maintains that his dynos produce "true horsepower" and that the readings given by Dynojet dynos are inaccurate and inflated.

Dynojet officials maintain that their dynos are accurate, and Dynojet has sold many times the number of dynos sold by Factory Pro Tuning.

The Factory Pro Tuning dyno at Daytona is being operated by Factory Pro Racing's Leigh Thomas.

Factory Pro Racing's Salvisberg claims that his dyno produces consistent readings without horsepower swings related to changing weather conditions.

Well there were many 03 G1k's running those numbers...go to gixxer.com and see some dyno charts. Look it up in Morotcyclist if you have to. My 01 was in the 140's stock...and the 03's were making about 10 hp more STOCK
