They look similar to what I've been calling phenolic resin cage bearings. I started using them when I had main bearing cages come apart in my Suzuki TS100 bucket. I've used them more recently in MB100 engines as main bearings. I've never had a problem with them. They weren't a whole lot more expensive if I recall.

any you guys tried these cages ? seems like they would need to be special ordered and maybe that adds a lot to the cost http://www.skf.com/binary/tcm:12-322...m_12-32271.pdf

H model had 2 seperate cranks with a coupling in the middle , on the outside of the coupling was the output gear that drove the jackshaft. So the crank was but a distant relative to the early TZs

Those bearings were especially made for Aprilia.
We had lots of problems because the 'shoulder' used to break off.
So they removed it, and instead supplied a loose ring.
They were used on all Aprilia engines, not just the RSA

I use SKF NJ 204 ECP C3 or FAG NJ 204 E TVP2 C3 (equivalent to the 6204 bearings) in my 50cc Derbi engine. 0,2...0,3 axial play and I never had a failure with up to 50h runtime, thats about the time the better crankshafts last

Not just British motorsport: ALL European motorsport could end. Funniest and scariest is that this would also apply to lawnmowers and mobility scooters.

Jus as well the IOM is not part of Britain, neither is Ireland.

The IOM and Northern Ireland are British. - Southern Ireland is a republic, they officially separated from Britain in 1949 (I think).
It's funny that when Eugene Laverty wins he prefers to have the Irish national anthem played and under the Irish Tri colour flag, whereas his brother Michael uses the Union Jack and has the British national anthem playing,
They come from Northern Ireland but at least now they can voice their preferences without controversy. (progress I guess!).

Both motorcycle racing and Rugby don't seem to recognize borders in Ireland and that's good!
