It's sold. It's still possible to order but it will take longer. PM me if needed.

This thread has been quiet for a while but if the sprockets are still available I would be interested.

The first solution that come to my mind was to hard anodize the aluminum sprockets.
That creates a layer of wear-resistant ceramic (aluminum oxide, far harder than steel) a bit less than 0.1 mm thickness.

The MMC aluminium sprockets are hard anodized but this wears through in a few thousand miles. They changed to a steel sprocket in early 2015

I just bit the bullet and updated my rear sprocket to steel. If you haven’t done it yet then make it your first upgrade. It really is a night and day improvement. My car had 6000miles on the original and it was making horrible noises and it always felt like something was grinding both accelerating and lifting off the throttle. All that was resolved with new sprocket and car is now taught, grind and wine free.

That's very surprising, if true, as hard anodize (Type III) has twice the wear resistance of case hardened steel. My guess is that Morgan mis-specified Type I or II, or the suppliers misread the drawings, or just did a bad job of it.

I have one sitting down at my house in France, that you would be very welcome to (only done 5k km) but not even sure I am going to able to get there at all this year. I am currently tied to the UK by the need for regular hospital visits for at least a few weeks more, even if Covid was not making it very difficult to get to France and back. France is possibly going to permit UK visitors from next week, subject the Indian variant not taking off over the week-end but of course, there would still be quarantine to deal with on the way back.
