I use King Bearing in Sparks nv. Drove there (close to Summit racing) gave them #s on bearings, (they cannot go by application), Japanese Koyos 4 regulars & the hub bearing were 52 bucks. Chinese are 4 bucks per cheaper.They have or can get any seal w seal size (right on seal will be #s like 10 24 32) this is seal size 10m wide, 24m inner 32m outer) They claim to be able to get any bearing, any seal. I've used them for 20+ years ( had a shop) & they are for real, Porsche trans bearings extreamly expensive, Got them from them @ 1/3 the cost! I went in cold (no ck for stock) on wheel brgs DT1c, had everything (as I knew they would) they take phone orders too, but you need #s on bearings!

Coincidence, I bought the bike in Reno, near Sparks. Got to see what size in front wheel, then order them.
