This is probably a naive question ...

Davis937 · April 28th, 2011, 10:10 PM

But, then again, maybe not ... I was wondering if a stock 2010 ninja 250 has more horse power than a stock 2007 ninja 250. If anyone has some specific numbers, I would appreciate that. Thanks ...

"...the older model makes one more horsepower than the new one. The older model actually makes more peak power than the new model: 27.46 hp (20.48 kW) @ 12,000 rpm for the 2004 compared with 26.4 hp (19.7 kW) @ 11,000 rpm for the 2008 carbureted model."

And that was a 2004, without flames.

You could probably add another 3 hp on that sweet looking silver 2007 with full flames.

Hope you are loving the bike.

Pre-gen models are lighter and faster and get better gas mileage with a history of rock-solid reliability. The new-gen is basically the same bike with an updated look, slightly improved suspension and brakes. They did make some "improvements" to the engine so only time will tell how reliable these bikes are.

Don't forget the centerstand comes with the pre-08 bikes

... thanks, Kelly! So I guess other folks have already been mulling over these kinds of comparisons, huh. Mahalo!

... thanks, Colin. I've been seeing so many different numbers and there seems to be no real consensus or agreement. Some even talk about rear tire HP (and I'm not quite sure what that means).

Hey, Chuck ... silver ninjas rule (especially if they have bright red flames). Thanks for asking ... yes, I am enjoying ... no, make that loving ... my bike more than I anticipated. It's sweet ... take good care and ride safe!

Hey Joon ... you know, I actually had "new generation" envy ... for awhile ... but I'm finding my 2007 is solid, fun, reliable, and need not take a back seat to any of the new generation ninjas ... very pleasantly surprised with the performance of my 2007 ... just love her! Take care and ride safe ...

Hey A ... yeah, the 2007 has a lot of little surprised. It's like finding all kinds of prizes in a cracker jack box! Take good care and stay safe ...

I'd say its more than a slight improvement atleast suspension wise, the pre gens I've ridden have felt considerably softer and mushy then the new gen which also has a preload adjustable rear shock giving it better handling characteristics, mid-range has been improved at the cost of a little top end, while adding about 20-30 more pounds making it a bit slower, reliablilty wise I've put 20k miles in two summers on my 09 and its never given me a problem that wasn't my fault, yet...

rear tire hp or bhp (brake horse power) is the amount of hp actually being delivered to the rear wheel and propelling you forward compared to the hp at the crank, which is essentially how much is produced at the engine. these bikes are rated at 32-33 hp at the crank, which translates to 26-27 hp after losing a few a horses in the drivetrain and transfer to the rear wheel.

Hey Ronin ... that makes sense. Thanks for taking the time to provide an explanation ... take care and ride safe!

Actually that's partly wrong. Brake horsepower (bhp or chp) is measured at the crank and has nothing to do with the brakes on the car or bike. That's the number you will typically see advertised by manufacturers. Wheel horsepower (whp) is measured on a dyno and is typically 15-25% lower than bhp due to drivetrain loss.

The brake is attached to the engine's crankshaft when measuring the engine's hp.
