thats what I thought, but he told me he was full throttle....I only raced him through first, my 1-2 always goes into N after 8k rpms...

I know the R6 is faster then an F4...his is FI, has more power and 20lbs lighter....just seems odd, someone who brags about some chip(that I have never heard of, nor has anybody else I have told) and a full yosh exhaust cant go by me....he said I could ride his bike next time were out...then I should know if somethings wrong with his bike, or if its just him

95hp at wheel maybe?
looking up online the 00 F4 has 110HP 374lbs(dry), and the 03 R6 has 121HP 357lbs (dry)
Those numbers are wrong. I promise. A dynotuned 2007 CBR 600RR with race gas, Leovince pipe, and a PCIII USB is a little over 110HP. And yes, your friend is an idiot. Is he confusing the Yamaha DeltaBox frame with some kind of delta chip? Or did he really spend $1100 on some eBay scam that makes his bike run that bad?

When they give HP numbers do they factor in RAM induction or is based on engine?

your talking about HP at the wheel....always going to be lower..F4 at the wheel from what people on this forum have said is aroung 90-95 HP

Yes he is an idiot...and no he didnt spend the money, said he has papers from the guy he bought the bike off of....hes not my friend, hes my friends friend...of course he did spend $6300 on a 03 R6 with 12k miles...I laughed when he told me that

Does anyone read the SuperBike mag out of the UK. Its a great publication, with lots of good info. Anyways, they used to compare all the different used bikes (600, 750, 1000, v-twin, etc..) in different classes. Reigning champ was the "99+ CBR F series", "best all-around bike that money could buy." Now I might be a little biased, but this does say alot. I can push away from my buddies 01 GSXR-600 and another friends 99 R6. Now a new bike probably not, but all and all the CBR was a great bike, easy to fix, and easy to get mods for it. I could have never made a better purchase. Peace

Well if the F4 makes about 90-95 HP at the rear tire then that would make it about 110HP at the crank. When a new vehicle be it car,truck or bike is HP rated it's always at the crank-not the wheels. A stock 1990 Mustang GT is rated at 225HP,but only put's about 200HP to the wheels.

I do know that my bike is damn fast for a older carbed 600. The same day I got my F4 I was looking at a 2001 R6 and I choose the F4-glad I did.

those #'s dont take into account the gain from the ram air either.

A friend of mine has an 05 R6 (the same as the newer R6-s) and his bike is no faster then mine. He has atwo bros pipe and a PC.With the sprocket kit, I pull from him pretty good. F4s arent as slow as people make them out to be.

I think when they rate bikes its always at the wheel? Since it would be hard to dyno a motorcycle engine without the transmission?
