New ducati single
- Thread starter bigpoppa
- Start date
Yup, they announced yesterday they're entering the MX arena and it'll have desmo valvetrain.
If Ducati wants to compete in MX, it would benefit them to bump up this engine to the 450cc max allowable in that competition class.
Also, I see this as a foot in the door for the Dakar rally as well, as that also has a 450cc restriction. Engine power is only one factor, we'll see how they do with weight savings, in order to knock the class-leader KTM off the top step of the power-to-weight podium.
Along with the new Desert X Rally model, Ducati is making fast inroads into the dirt market. I'm liking what I see. Could be a few more red machines in the garage in the near future!

Should be a... Blast!Sorry. Isn't it a 400cc MX bike and a 650cc streeter?
The new Ducati mono 659 CC. 83,4 HP, 10250 rpm 70% of max torque available over 3000rpm.desmo with a valve service every 30.000 km.
Isn't the "70% of max torque available over 3000rpm" part a game changer? How does that compare... I don't keep up... but sounds impressive to me! The only other motor I know off that comes on the pipe that hard, that early is a Norton, and it's a freight train... and a twin
4 1/4" bore will do that for ya....

... always the cynic
New and improved 30,000k valve service interval
Isn't that kinda academic, when the 116mm slipper piston is only gonna last 12,000k. (long lasting singles have big, long skirt "soup can" like pistons. Short slipper pistons cant in the barrel, cuz they have no skirt. Singles EAT pistons, slipper pistons make it worse)

The Lives Of Pistons
Modern piston crowns and combustion chambers are nearly flat, resulting in minimum surface area, but that hasn’t always been the case.

Most 450 singles call for a new piston every 50 to 100 hours of use.... always the cynic

85 hp from a single is pretty impressive.
13:1 compression may be trouble. That sounds like 94 octane territory if you're lucky. Wouldn't be that surprised if it needs higher than that to make full power (timing pulled with 94 octane to try to preserve itself).
Anybody found a weight for this thing?

I hope Ducati has done their homework, otherwise this thing will have a really short fuse.
On the flip side - spec racing series anyone ?

77.5 hp at the output shaft (after transmission losses) - that's going to fly in the proper chassis.
