The V4S doesn't have titanium con rods nor does it have the cam profile of the V4R or the rev limit of the V4R. I expect the workshop technical bulletin for the V4S to recommend less replacement. I also expect over time as more and more data is collected for the servicing to be changed to reflect what is actually happening. Andy
It also depends what revs you're running to. The engines will last a lot longer if you're not constantly on the limit.
Has anyone asked for the race service schedule for other Ducati’s? All of the owners manuals state the same thing - even the humble 959:
For those of you who are interested in facts. https://www.racepagesdigital.com/pi...estructive-forces-at-work-inside-your-engine/ Below are the Mean Piston Speeds in feet per minute for the following bikes based on the maximum Rev limit on each bike. For most bikes this is only possible in 6th gear. If you read the article you will see than engine designers use this as gauge of reliability - it also explains why the V4 and the V4R would both have the same service schedule. If you check the user manual for both bikes the road use schedule is the same and no different from any other panigale. They all state clearly that the schedule would be different for race use. If anyone has a copy of the race service schedule for a 959 I for one would be very interested! Desmosedici RR - 3965 —- 14200 rpm 1199 — 4508 —- 11300 rpm 959 —- 4587 —- 11500 rpm 1199/1299 — 4787 —- 12000 rpm Panigale R — 4986 —- 12500 rpm V4 —- 5246 —- 15000 rpm V4R —- 5240 —- 16500 rpm
Hence my comments. Especially if this applies to standard V4 if used for track days!! Makes a 65k bmw with 3 yr / 5k miles warranty on track seem cheap!
I imagine there will be a few "low mileage" bikes with pristine bodywork for sale in a couple of seasons time. One careful owner, never tracked (cough cough).
