I've read that 2007 cbr 600rr is suppose to have a higher redline do u guys think that it'll have alot less power down low affecting its rideability on public streets? I personaly love the look of the 07 600rr and want to order one for march, but if its gonna have a power band like the newer Yamaha r6 i'll probably go with a 636 or a triumph 675. The 2007 zx6r looks good aswell but it suppose to have a higher rev also. What do u guys think?

why would that effect ride on public roads to the point of going with something else.....I highly doubt they will trade low end away, but i've been wrong before

On one of the links posted here about the new '07 it said that they did some engine modification to raise the midrange but that there was no loss of power any where else.

 

[slvrblckrr]

Just because it has a higher rev capacity doesn't mean they're sacrificing low end power. I don't really consider any I4 600 to have "low-end power" but the new R6 really changed my perception of that.
Honda claims that the new RR has improved mid range due to some modifications they made. I think it also has a flapper in the intake as well as the exhaust valve. These two things would improve on/off throttle transitions and mid range power.

If i were you, i'd just wait until magazines start testing the bike to make judgements not based on looks.

I thought I read that the redline on the 07 was still 15K..

If it is higher, I'd bet its no higher than 16,200.. but raising the redline almost always trades low-end for top-end..

 

[snikwad]

i cant see Honda dropping mid and low end power to make more at the top, if anyone knows the importance of midrange its Honda, remember they were the ones that added a second set of injectors... And i didnt see any mention in any article of an increased redline.

 

[nuber]

Maybe i was thinking of the zx6r's increased redline not the cbr's. sorry bout that

FWIW: Today was the second time (from a different person) that I've heard a "highly" respected rider indicate that the new RR flat-out rocks & rolls when comp'd to the R6.

The 07 cbr actually redlines at 15,000 instead of 15,500 that the 06 produced. Peak horsepower is the same though at 13,500.

Look at it this way, the lack of low-end is not an issue on the track, so why worry about it.

i didnt know that 06 redlines at 15500, cool. i thought it was the same 15k as the 03-04s

Actually your right it is 15k, dont know why i thought it was 15500.

 

[snikwad]

Your thinking of the old R6, i know those used to have an indicated 15500 redline.

Same damn redline as the 06... midrange and top end is what u should concentrate on, espeically for a 600. If u want low end and wheelies, get a 1000.

The 07 cbr does have a higher redline I've read it in a few places....2 reports (1)15,500
(2)16,200

ok i found a lil something after a quick seacrh...

This new engine is fed by 40mm throttle bodies to valves we assume are the same sizes as last year's bike, already the largest in its class. A new centrally located ram-air duct similar to the RC51 gulps the atmosphere into an airbox now 0.7 liters larger. The intake charge is squeezed at a slightly higher compression ratio of 12.2:1 by forged aluminum pistons that are now shot-peened for greater durability. A new knock sensor maintains optimal spark advance and makes compensation for lower-octane fuel. Lighter internals allow for a 500-rpm higher redline, now up to 15,700 revs, which should put it close to the Yamaha R6's true redline. A new stainless steel exhaust system, finally with an ECU-controlled back-pressure valve, has a smaller muffler that now exits above the new LED taillight.

Honda says the powerband of the new CBR is smoother and more linear than before, and it has a "noticeably stronger pull" between 7000 and 10,000 rpm. An improved powerband is a must, because Honda claims 118 horsepower at 13,500 rpm, only 3 ponies up on its claim for the old bike at 13,000 revs. Peak torque of 48.7 lb-ft is identical to the previous year and 250 rpm higher.

Really not a big deal, honda's been known for there RPM/Speedo accuracy compared to the other brands so no worries on the faulty Tacho readings side. All of that give, I would still buy it, I think people need to wake up and smell what they are buying, your not going to get a torque monster out of a 600. If u want low end and true midrange, get a vtwin, otherwise your best bet is a Gixxer 750 or a Triumph 675.

 

[snikwad]

While Honda went to great lengths to make a dimensionally much smaller engine it goes without saying that a similar amount of effort was spent on ensuring the output was anything but smaller. Honda claim that the power delivery is stronger throughout the entire rev range with a major improvement in the useful 7,000 to 10,000rpm range.

Thats yeat another article confirming improved midrange, and for me it wasnt lacking compared to the others, but im featherweight anyway so it prolly doesnt matter. Right now my major concern with this bike is if we'll get Bridgstones on it or Dunlops.

 

[Fooldog01]

Kind of funny that the redline on the new CBR will be close to the R6's ACTUAL redline, when it is 1,800 RPM lower than Yamahas CLAIMED redline. Its an outrage that Yamaha lied by over 1k rpm (and then some). 200-300rpm? Fine. 1,800 rpm? give me a break.

Sorry I know this has been talked about before but that post by Snikwad pissed me off.

 

[snikwad]

my post, which one, #16, or 18?
Well just be happy you ride a Honda, and regardless of what Rossi rides, Honda got the Manufacturer cup. You ride the best machines. We just dont have the best rider anymore, but we have one good one and one jackass that can win races sometimes
