Great test, it's amazing how much power and top speed they can get out of a lowly six hundred cc motorcycle now days. Amazing technology. I truly believe we are living in the heady days of technology driven performance, with some of the best motorcycle EVER produced. Just wait until the direct injected two stroke makes its long planned manufacture, then the gates of hell will be ripped right off thier hinges.

Direct injection is cool - it is more efficient with fuel, allows higher compression and more torque as a result. I wonder if it could keep up with a 600 spinning at 15,000 rpm though. Who knows.

The 750 has always been the "Goldilocks GSXR" in my opinion. More grunt than the 600, better handling (mainly through less spinning mass vs. less weight) than the 1000. Looking forward to that writeup.

What a cool track day toy these new 600s are. Not so sure about using them on the street though. Ridden with 600s on the street - it is fun sport on a 1000 to simply roll it on in a tall gear and run through the power range while never shifting while the poor guy on the 600 tap dances on the lever...

You do now. The answer is no. I asked this same question to BMW's powertrain engineer leader last week. He says GDI not likely for motorcycles, as it doesn’t yet work above 10K rpm. He believes the next motorcycle engine development will be variable valve tech.

Isn't Honda's VTEC just that?

Nice writeup. I can't imagine this bike anywhere but the track. Not that it wouldn't be fun to pull 15,000 RPM wheelies over that little bridge leading into my development, but the neighbors have no appreciation for the finer things.

Thanks Kevin, very interesting. DI is all the rage on cars now and very effective there. Perhaps we will see it appear on cruisers, with their lower rev ceilings.

Never forget my day with Jason Pridmore CLASS school. He did amazing things on that GSXR750, like backing it in at horrifying speeds, and passing A Group riders with me on the back, about peeing in my leathers. I have no illusions - these things are so much better than I am!

Yep, DI could make sense on cruiser motors. I'll bet H-D is working on it. And, BTW, BMW hasn't forgotten about the huge cruiser market...

I've also had the eye-opening pleasure of riding on back of the Pridmores - not to be believed until experienced and HIGHLY recommended. Jason was passing number-plated race bikes with me on the back of his Katana!

That goofy V-4 MOTUS bike Pushrod posted today is DI.

My 06 speed6 is DI and shouldnt of been. Flattest top end of any turbo Ive driven.

Direct Injection works best in two-cycle motors, because you have no valve train, or other reciprocating parts like valve springs, valves, camshafts, rocker arms, etc. All you have is a piston, and exhaust port, and a powerful intake injector. An Orbital DI motor that Ford put in a Escort Rally car back in the middle 80's put out 300 hp, and weighed 100 lbs. The FIM banned it the next season, and GM bought the patent from Ford, only to be shelved for 20 years.

How would you like a car that got 1/2 the emssions of a fuel injected four cycle, twice the power at half the weight? And never needed a cam belt changed, a valve job, or other nonsense that four strokes live with.

KTM abd a company in China are perfecting it for street use, should be out on the market by 2012 or so.
