ducati engines

repsolrider07 · 02-09-2009, 6:22 AM

when are ducati going to stop making larger and larger engine capacitys the 748 is nearly a 900 and the 916 is a 1200 can anybody shed some light on this
and are these cock machines going to be a 2 litre in the not to distant future.

My take is that they were doing this to keep up HP wise to the 600's and 1000 cc jap bike classes. It takes larger displacement to make similar horsepower from a V twin unless they use very exotic materials.

I always felt it wasn't fair but I have now changed. They are stuck on their engine design because of their following and heritage so they can't really change it. Kind of like Harley with their engine design. It'll never make any real streetable power because that design does not work well with high compression.

Ducati did have a departure in MotoGP with a V-4 desmo engine with a big bang firing order to make the power they needed to compete. This was accepted because it's a special series I think.

I ride a 07 repsol honda (171bhp tested) and a 848 cock machine! Its called evolution...that's how Honda got to the RR8/9!

Is your frustration that you can't catch the Ducati with a CBR1000RR? (ONLY KIDDING!)

As for the racing, don't forget that Honda raced the VTR1000 in the 750 class not so long ago.."Coling Edwards in WSB"

That's not quite correct. Being a twin its class capacity was 1000cc in WSB. Inline fours were restricted to 750cc.
They were different capacities but they were racing in the same class - Superbike.
It began with Ducati who refused to even attempt to build a 750 to compete against the Jap 750's. The only way WSB could get them to come onboard was by giving them a 33% capacity advantage over the rest of the field.
Last year they threatened to pull out again unless they were given another 200cc advantage.

To expand on what Larry has said. The rules allowed 1000cc twins, 900cc triples and 750cc fours. The math that was used looked at the volume of air the engines could pump; all three were close to one another. The difference that one had was that the twins could put the power to the ground better.

Ducati just doesn't want to change.

I agree fully..

Ducati's "we're going to pull out unless" attatude was out of order! The 999 was a winning bike without a cc advantage! So was the 1098, the 1098R caused the "we're going unless"

The twins do have a dissadvantage over the fours, its not that they cant get good power, it's just that good power from a twin costs bucks...loads of bucks to get the same or more power than the fours.
I do feel that if its a 1000cc class then a 1000cc's it is, no more even if you do have twins! The twins do have advantages of there own..I would have also liked Honda to have cleaned up the VTR so they could still produce them, even have added 200cc to keep in line with the 1098R, it would have been fun to see how they went together.

I love all the bikes on the grid! Mostly the Hondas..!!

The problem with twins is the engine is physically enormous compared to an inline four.
The 1098 was a winning bike without a capacity advantage?
It had 10% more than everybody else :-)

don't get me wrong i think ducati have given sbk a more broader audience and
who can forget the foggy,corser,chili,slight,edwards,yanagawa, era ,slip
streaming each other at monza and hockenhiem during some of the best racing i have seen, i have heard a few rumours about japanese running
different engine configurations v4/v5 for instance but will the bikes still be 1000cc? and is the sbk run by italians!

According to the website the lineup for this season all the Japs are inline-fours. Ducati have the 1098 listed but that might be a typo?
Aprilia are running the V4 1000 and BMW have the 1000RR which I assume is an inline-four?

I believe the 1098R is an 1198cc Larry. The badging had something to do with homologation. According to the new rules (2008) they were able to run 1200cc but only had a 1098 for the street. Call it an R and put in the big motor and it became legal.

SBK is only broadcast on cable down here so I don't even see it :-)
It's almost always better racing than MotoGP but professional racing drives up retail prices enough already. I'm not going to encourage them by paying to watch it.

repsolrider07 · 02-11-2009, 6:20 AM

the motorcycle racing is the only thing worth paying for on foxtel ,apart from
the premier league but i,m a pom so there you go.

arthurbikemad · 02-11-2009, 5:37 PM

I pay for Sky TV mainly for the racing.
I love it all but WSB is much more interesting most of the time, and hey at least we all ride/race bikes that are based on them too (or visaversa), so you can sort of relate to the racing! Unlike MGP.
