Do you think it might be they've not updated the animation ?

Perhaps you tell why EVERYONE else uses plain ?
It's not everyone and the benefits of "plain" versus needle and ball are well understood.
And for your information I don't think there is mutch refriction betwen piston and cylinder thanx to modern oils and if there was all cars would have hard crome liners by now.
erm, "modern" engines have to have LESS oil in the ring/piston/wall interface to kleep emissions low. Cars pushing the hp/l efficiency limits DO have nikasil etc linings !!
You moam the same shit over and over again and don't answer the actual question, just like politicians and internet scams.
Yep, just liek Bush said "everyone" supported invading Iraq, you quite "everyone" using plain bearings. Pot, kettle, black <-- add verba and arrange in to a sentence
Motorbike engines is full off ball bearings just like your revetec and gues what? They don't last 500 000km without a overhaul.
500K ? Who cares !!!
The downside of increasing hp/l is that the extra stresses WILL reduce engien life. But who cares, with modern emission standards coming it will not be possible to maintain stricter emissions in older engines through wear anyway !!!
And it was suposed to be sooo well balanced, but now on the x4 I can see all the balance shafts sceptics predicted.
erm, it's a different piston confiuration so hence removing an aspect of the self-balancing.
WHat IS your engineering background ? Cos it's pretty obvious why the X4 needs balancer shafts and why for that market they moved away from the original layout for that market !
Can a moderator please change the title on this thread it's was a shithead moderator that split it and gave it this name annyway.
Attacking revetec is bad enough. Attacking a moderator in that manner is about to get you a ban.
It should say Revetec! Brilliant or Scam.
