Getting back on track here. Look at some of the pics of the 18's and you'll see the louvers opened up over the top of the driven clutch, the 17 prototypes had these open as well, but the production 17's had them closed off, easy enough to open up however if one feels they will do any good. I was looking at venting some more in front and out the back of the clutch side area, not that the clutches run hot at all, but cooler is always better. Holes are free and FrogSkinz are cheap, both go a long way.
Also you will see vents above the chaincase area on the 18's behind the turbo too.
I'm sure they will be coming with updated rollers in the driven like the ones that were given to the guys with 17's that flat spotted their rollers.
As for other updates, who knows, the chassis has been dialed over the years and the Yamaha 998 seems pretty perfect, trouble free and bullet proof so far. I doubt there will be many if any updates or changes other than the ones already brought out for the 17's. Certainly nothing major anyway.
Be nice if Cat added drain and fill plugs on the chaincase but that won't happen, their just like Doo that way now.
