After much speculation about this bike, the numbers are in. Here's a dyno run of the GT650R, done by MidAmerica Powersports in Independence, MO.

It looks like peak Hp is just a bit on the far side of 50hp, quite a bit less than the SV650 and just a tad stronger than the Ninja500/GS500 twins. Torque curve looks flat too, around 31lbft, no real peaks and valleys for a newb to contend with.

Very nice graphs! Good find.

I'd really like to ride one of these sometime. By the number, it looks like it's on the very edge of newbie-dom... maybe a tad high for my relatively conservative tastes.

What's more important is how mangeable the weight is, how quickly it steers, and how friendly the brakes are... I'm sure that info is everywhere, but I haven't heard it from someone's mouth on this site yet.

I can't find it on Google - do you know offhand what the MSRP on one of these is?

They are tall in the saddle in the saddle and have an aggressive forward seating position (low clipons). Not good for smaller/shorter new riders... Taller riders? prolly ok.

From the spec sheets I've seen, the size is about that of an SV 650S. I've yet to find a local dealer so I can't ride my SV down for a side by side comparison.

HP at the crank is meaningless. BrakeHorsepower is the best indicator, which I guess is about the same as True HPA.
One of those HP values are pure BS, No way will the bike lose 26% of it's HP between the crank & the rear wheel.:???:

Also, they measured a lot of torque at LESS THAN 100RPM :-D
Of course the 1st graph shows max torque at 80,000RPM :lol2:

Brake horsepower is not the same thing as wheel horsepower - it just means that they used a brake type dyno rather than an innertial dyno. While a brake type dyno can be more accurate in some cases, brake type chassis dynos for motorcycles are pretty rare. It's very rare to see the term "brake horsepower" used to describe anything other than the horsepower at the crank.

No problem. Glad to help. :)

I've been researching this company for a while now and still trying to make a decision. I'm looking at the GV650 (cruiser) as a first bike, but I'm not sure if 70HP is too much for a first bike.

In other countries, they offer a restricted version that is rated at 35ish HP. They use carb slides to restrict it. The US version doesn't have this...I kinda wish it did. At least you could get comfortable with it then after a few hundred to a thousand miles, you could de-restrict it and it would be like getting a whole new bike.

anyway, what do you guys think? Is 70HP too much for a first bike?

That's an interesting idea.....a Jeckyl & Hyde bike for newbies
