Thanks

Good afternoon.

I've not heard of them, but as they don't state which make of bearing they are, I would be suspicious....There are a lot of 'plastic' bearings around.

If you wish to go for taper rollers. Get Koyo bearings. These are excellent. You will need a 32006JRRS bearing for the bottom. This has a built in seal, & a 32006JR for the top.

Cheers.

Are those part No's relevant for the curvy models?

No, curvy top is smaller, 32004 maybe but check that yourself as I can't remember.
Bottom is same 32006 both.

Marksman will sell you those koyo if you ask.

Silly question....but do the bearings i buy need to have the letters after 32006 or can they just state the 32006???

I think the JR is steel cage code and RS is rubber seal.
Not 100% about JR part though, if you just ask for 32006 you will get non sealed ones but they'll be right size.

The Curvy model uses a 32005 bearing at the top.

Indeed the RS denotes that the bearing has a rubber seal.

As with most consumables, bearings vary widely in quality. I started using Koyo bearings long before YC was even in Nappies

.
I had noticed that Yamaha steering bearings lasted roughly twice as long a Suzuki's. Even when correctly greased. Yamaha used Koyo bearings, & Suzuki used NTN.
Don't skimp & buy cheapo or unknown make bearings. You'll be doing the job again sooner than you think.

Cheers.
