I want to upgrade to sealed wheel bearings.

Old Britt's site says that the bearing bore and axle must be modified to accept the sealed bearings they sell.

Can anyone point me to a source of bearings that are a like-for-like swap, i.e. no additional maching required?

Hi there, good idea!
The single row bearing exist in a sealed form , so instead of 6203 , you ask for 6203 EE, they are both metric at 17x40x12 mm, the problem arises with the double row , which is 4203 on the open form at 17x40x16, but on the sealed form only exits(?) in 3203 (suffix depends of the manufacturer , but size are 17x40x17.5, so you must shorten your dummy axle (the spacer iside the hub ) by 1.5 mm(at least), to allow proper setting (otherwise it will protrude by 1.5 mm; another solution I had found are the 2203 which exist in sealed form and are 17x40x16, but they are self aligning double row bearings (little bit more expansive here in France , but I have good discount on bearings ....), the fact they self aligning doesn't bother me any more (unless somebody tells me it's no convenient for that use!) .my two cents......Pierre

I've used the single row sealed bearing on both sides for years without a problem. You'll need to make up a spacer for the double row side though.

The Unapproachable Norton Commando

At the end of 1967 the Norton Commando was announced.

The Norton Commando was greeted with a certain amount of scepticism because on first sight the commando appeared to comprise of the old Norton Dominator twin cylinder engine mounted at an inclined angle in a set of new cylinder parts.

It was not realized that the new Norton Commando Isolastic method of engine suspension damped out all engine vibration and produced a machine which had uncanny smoothness for a vertical twin. In due course the critics were silenced and the Norton Commando had the distinction of being regarded as the first of todays so called superbikes. There can be little doubt that the original design concept of the Norton Commando has proved correct, since comparatively few modifications of any real consequence have been made since production commenced during 1968.

Now nearly 40 years later Norton Commando riders like us are a breed of our own, and as far as we are concerned its still more fun to go for a blat on the old Norton Commando, and fast. As a Norton Commando owner and enthusiast, my goal here is to promote and give credit to those who keep the Norton name going.

It is more deserving to give credit to the Commando itself, for after all these years it continues to be respected. The original Commando designers like John Favill are those who deserve the credit for developing this incredible motorcycle.

The Norton Commando Roadster and Interstate of the late seventies, never died. Although the Norton Villiers factory dispersed the tradition lived on. Today Kenny Dreer in the USA is developing the new 952 CC Norton. What a great looking bike this is, and its engineering is still based on the original layout. It will be interesting to see how the new 952CC Norton does in todays tough motorcycle market. One thing is for sure, I would own one if I could afford it.
