RGS steering head bearings

[Dellortoman]

Does anyone have the reference numbers for the RGS steering head bearings?

JLO's website lists the bearings for 1000/1200 ...

Steering upper 6205-2RS,  25 x 52 x 15mm,  deep groove ball bearing
Steering lower 30205,  25 x 52 x 16,50mm,  tapered roller bearing

Which is correct for the 180 triples, but the RGS appears to be different because it has tapered rollers top and bottom. They appear to be the same (30205). Can someone confirm?

I tried searching this and other sources, but so far have come up with nothing.

Cam,

The early triples, up to RGS series, had the ball bearing upper, tapered lower.

RGS had mixed.

Tapered bearings can be fitted to the early bikes, but it buggers up the spacing between the yokes, making correct fitment of the headlight bracket tubes a pain in the arse.

HTH,

Hi Cam,

Confirming Piet's information, RGS steering head bearings are definitely taper rollers top and bottom - 30205 - and don't forget the spacers/washers in the headstock and on the bottom of the stem

HTH,

Red is correct about fitting two taper rollers to the 180, but the fiddle is well worth it, I would not go back.
I just fitted everything up, and measured the headlight tubes, then  took the top yolk (triple clamp) off and fitted a spacer ring into the bottom of the tube,(pressed in on a fly press) to exend it, yolk back on, job done, and permanent, well it seems like it, the originals lasted about 50 or 60,000 miles the repacement tapers  (and bear in mind steers better, or so the tuners would have you believe) have lasted untill 200,000 and still work OK.

ps while it was apart I wish I had tapped a pair of greeese nipples into the right place on the headstock
