The 1125 is barely clearing 30 mpg?! Crap... THAT'S a deal-breaker right there. My Ss routinely gets about 53 mpg. There's no way I could justify a CR like that. That drops the CR down from "practical and fun" to just "fun".

Hell, my Mustang GT gets 27 mpg!

SM - stay tuned - the improvmenets to the '09s all address fueling issues, and they're claiming 53mpg highway for the 1125R this year.

yup,
swordsman,
thats what stopped me from putting down a deposit at the dealer this morning when i went to get some parts.
i fill up my XB12XT every third or fourth day on my commute....around 17 bucks in socal, with the CR it would be like every other day........defeating the purpose of saving money on gas.
If they can make 53mpg on the CR i will probably change my mind, however i still told them to call me when it comes in for a test ride!

I don't get 53 out of my Uly.

Best Ive EVER done is 50.

If they can get high 40's or low 50's, they would have mileage better than ANY other equivalent competitor.

Sold my XB... It had become a garage queen since I bought the 1125r. Everything an XB can do, the 1125r does better. However, the XB does seem to have more low end grunt. The 1125r is singing its song the best up around and past 8k rpm.

I'm having a hard time understanding why people are so shocked that the fuel mileage is down on the 1125r/cr. You've got the same basic engine layout (v-twin), a few less CC's than an xb12, and is making around 40 more horsepower. It takes fuel to make power. Unless I'm missing something, it should be expected that the 1125 get worse mileage than an xb.

Similar displacements. 1125 Power is only on top end. Thats not where we drive. Commuting should bring in mid 40ish numbers. Driven for fun, mid 30ish

If I can sell my ancient X1, I'll get a 1125r. Can't afford two street bikes and keep the wife. Need the wife to take care of the kids. ; )

On my 55 mile commute I get low 40's. I usually run in 5th or 6th taching 3,500-4,000 w/o any issues. Yeah I'd like a few more mpg (like anyone) and that may happen with the next mapping update.

Brad, please take into account that the engine has to be designed as a system. If you optimize HP in one range, it will make a difference in other rpm ranges. It is a VERY complex set of parameters and physical constraints that drive performance and mpg.

If this was true why would the auto mfg's be standing on their collective heads trying to get both, at the same time. Sometimes both cannot be achieved on the same engine.

I don't think that's necessarily the case. Being a slightly smaller displacement, and still a V-twin, I don't see any reason the fuel map couldn't be tuned in such a way that the lower throttle positions used in cruising were every bit as fuel efficient as an XB. There's no need to have 40 extra HP when the throttle is barely cracked.

Blasphemy!! Say penance to the gods of speed!!


Yeah, more MPG would be nice, but personally I didn't buy this bike to save the planet... I bought it to go fast and look good doing so. It does both well.

Doerman, Unibear and Zac,

Thanks for answering my questions, they were very helpful. The more I read and look at photos, the more I think the CR might be for me...

Does your Stang get up to 60 in less than 3 seconds? Nuff said.}

Your point is valid, but I think point was that an engine 4 1/2 times the size, making more twice the power, and pulling almost 10 times the weight, gets almost as good gas mileage.

Gearing -

I get 26 mpg or so in my Z-28.
LT-1/6 speed/Posi
That why low rpm rideability is important.

"1125 Power is only on top end."

Huh? You must be thinking about the Ducati 1098 or another more race-tuned V-Twin sportbike. The 1125 exhibits amazingly strong and consistent torque output all the way from 4K through to red line at 10,500 rpm. You won't find another liter class twin cylinder sportbike with better/wider powerband characteristics. Period.

Anyone else totally dig seeing that "Buell Muffler" under the KTM?

I recall so clearly the outcries about how foolish it was when introduced. Ever since Honda showed it on the NAS I've been beaming with the pride of industry wide capitulation.

Erik didn't invent the concept. . . he just made it work.

Hey Blake, what mods did u do to get the extra power? new torque curve looks alot flatter...especially from 5-6k

Thats not a Buell muffler, maybe Buell placement but that ones is not covered in rust and is integrated into the design.

I think the point was not that the 1125R didn't make power on the bottom end, but that the 1125R doesn't make any more power than an XB12 except for on the top end, implying that the 1125R should get similar mileage to the XB12 during low RPM cruise.

How much does that RC8 cost?

And what's it's weight balance?

And why isn't the swingarm pointed in the right direction?

Wow, are all you guys looking at them too?


It has a front wheel weight bias and an extended swingarm to help keep it planted during acceleration. It is priced below the 1098. They aimed for the top. Even thou they did not begin developing this bike 25 years ago, I think they slapped together an ok ride as far as the reviews state.

I didn't ask how long the swinger was... I asked why it wasn't pointed it the right direction : ).

No : ), I'm not looking at them.


They do look good to my eye, but for some reason they just don't do it for me.

I was wondering the same thing. The engine looks to sit pretty far back.

"And what's it's weight balance?"

do you really believe that the KTM guys don´t know how to build a "ready to race" bike?
make a demo-ride and you will see, the RC8 is build from riders for riders - probably more than the 1125R. its chassis/suspension-unit works excellent.
and taste the front-brakes (best on a racetrack) - probably you never want your ZTL back... ZTL is a cool thing for bikes like my XB, but its performance is not state of the art for a hard ridden 146HP bike.

disadvantages? no belt drive (imho), no slipper clutch, +2.500 € (in GER)

advantages? more power & torque, better chassis, better brakes, more adjustable, stainless muffler, steering damper

whats your problem with the swingarm? it works... very well...

"implying that the 1125R should get similar mileage to the XB12 during low RPM cruise."

Shorter stroke, bigger bore, and plain bearings dictate otherwise. Engine configuration matters. There is no free lunch. If you want bigger power and higher revs, fuel efficiency at cruise will suffer accordingly.

The only time(s) that they've raced that I know of, 1125R racers have soundly beaten the RC8.

Conventional Brembo front brakes work well, but they hinder handling by increasing the unsprung mass of the front wheel/brake/fork assembly.

When you see a ZTL equipped Buell driving around the competition while leaned over in a turn, you may begin to understand the advantage that reduced unsprung mass provides.
