Engine specs 03 vs 09

I was looking at an 09 today and the guy told me that it has a ton more power than the previous models. I have an 03 and I call bs. I don't think there can be a whole lot of difference. It seems any upgrades in the new generation were minimal. Am I off base here? Is there any noticeable difference in power?

The 09 does have a bit more power then the 03...... But it also has more weight so I doubt it would be any noticeable difference in the 2. The handling and braking might be a bit better on road with the 09 however

The difference in power and torque between model years resides in marketing copy only, IMHO.

The fundamentals (compression ratio, carbretion, valve timing, intake porting, exhaust system, etc.) have not changed significantly in over 25 years of production.

Expecting significant power increases with the same hand of cards dealt over a generation ago seems unrealistic, to me. Even Kawasaki service manuals remain conservative when disclosing performance figures.

According to mcnews.com the 07 has 34 hp and weighs 409 pounds. The 08 has 36 hp and weighs 428 lbs (whp and wet weight).

So the gen II in an insignificant sample size has 6% increase in power and 4.6% increase in mass.
