Oil recommendation for cbr900rr track bike

[userfriendly]

I wonder if those Caterpillar TO-4s would fit.
I think the requirement is no VIIs, wet clutch very specific and minimum HTHS for SAE 30 of 3.5 or 3.7, I forget which.

Someone mentioned Delo 400 15W30 as being 3.7 HTHS.

I don't doubt that SAE 30s will produce better power than SAE 40s, and the engines may run cooler too.

But, the point is minimum HTHS not KV100 #s which obsoletes the SAE grade scale.

I agree but I would add Motul 5w30 and M1 5w30 because there is mounting evidence of no
gear pitting among real riders on actual motorcycles during the rigors of track days...
