Do you believe a claim by Kymco of 33 hp from 299cc?

Introducing the Downtown 300i. "Kymco USA's President Eric Bondy called it a 'GSX-R, except it's a scooter.'"

The article is about Kymco's US models for 2010. The best line in the article: "The Quannon gets up to 45 mph as quickly as most cars (as long as they don't know they're racing you)."

Motorcycle Daily has never written a negative review, TMK. Call them "moto journo junket junkies"

I want to see that. Almost like a burgman 400cc from suzuki.

33hp from 299cc yes. From a 4 stroke it's doable, with the current restrictions on emissions it would be hard.
Is there any bike shops with dyno in Taipei or Taiwan at all?

not possible sorry!.
I say 22bhp

CPI SM250 is 250cc and 24hp right?

The factory claims 24 hp @ 8000 rpm, but I've not seen a dyno plot.

The Zook DRZ400 engine was designed by Yoshimura, and produces about 33 hp in stock form, and there are plenty of dyno plots to confirm that. I don't see how Kymco's engine design skills can surpass those of Yoshimura.

Taiwan horses are smaller and less powerful, so I can see those numbers adding up.

The Kymco Downtown 300i has the new G5 Kymco engine. It's specifications are: 298.9cc, max horsepower 32.78/8000 ps/rpm, max torque 24.5/6500 Nm/rpm. On a dyno run in Greece it performed 32ps on wheel on the first run and after 3 more runs it performed 31,3 ps on wheel. It can do 0-100 in 7,5 seconds, it reaches 140 km/h easily, 150 km/h with patience and can hit 160km/h in downhill.

Ummmm...... No. Although, they do not have a record of publishing false claims AFAIK. When it's too embarrassing, they usually don't publish anything at all.

Looking at the speedo im saying 20bhp, if it had over 30bhp it would fly to 100 not crawl like that!.
My Z-125 (272cc) is faster than that and weighs 130kg's+

G5 kymco engine.......... hmm kymco make a scooter called a G5 which uses a larger GY6 engine with a 4 valve head, its EXACTLY a GY6 but its similar in dimensions at the bottom end and cvt.
That engine can be bored and stroked to 300cc+............ i wonder.
