im looking , hahaha i know what you mean though. but seriously, i dont know of a front wheel bearing kit for my falcon for less than $40. but i also think my falcon wouldnt pull 36,000 + Rpm either. . 
if the engines in good shape, then its worth the bearings. much worse replacing one that the crank has shifted a little, and smashed teh conrod into the piston, and the liner wont come out anymore.... haha thats from experience as well.

high speed bearing is always expensive.
I know ppl using TKO bearing in some NovaRossi engines. Maybe you can try that.

TKO bearings are excellent. Also ABEC 35 and Boca have better deals on good engine bearings. As much as I love Novarossi, I'm never going to pay those prices for bearings.

Novarossi bearings not only very high quality (made by SKF), also they have one future which they patented long time ago (BTW it wasn't their development, but they were fast to do patent), their main bearing has offset race for balls. This future is decreasing shaft flex under running conditions tramendosly. The only thing is-they needs to be install in right direction (A MUST!!!) Otherwise engine will be ruined pretty fast.
If it's me, I will never put anything in Novarossi, but their bearings. This applyed only for main bearing, not for front.
Here is simple pcs which will show difference.
I have attached old pics so you can see difference.
I hope it helps

Lets see now a Falcon weighs about 1700kg so 1 set of wheel bearings is holding up about 425kg and lasts 100,000kms or more. Not a bad deal compared to a couple of Novarossi bearings at $100, eh?

I doubt that.... SKF bearings do have a much better quality. The quality from NR differs a lot and today they are the worst I have ever seen, within 3 liters of use they are giving problems already.
For the front bearing I have some cheapo standard bearings from 2 dollar a piece and they do fine. NR is only creating weird sizes (25.4mm, 25.8mm etc) to prevent people going to get the bearings at a normal bearing shop.

Well, I am not giving executive order to you or anybody to use NR bearings, I just shared my knowlodge. You can use whatever is convinient for you-I am perfectly fine with that.

Thanks guys. One more question. I am looking on the Boca site they list ceramics of the correct dimensions but the rear bearing if you choose steel is only 5mm in width not 6mm per NR. What effect will this have??? Will it let the crank walk back and forth until it busts the conrod or piston or gudgeon??

TKO also have offset races. I'm not sure but I think Boca and ABEC 35 do as well.
