Well spotted Bob!

I guess (to me ) the important bit is that you can benefit from the training despite the bike not being able to make the NSL. With respect to the recommendation for test, I assume it would be up to the observer to discuss with the candidate the suitability of the machinery. Maybe there may be the possibility of using a rented/loaned bike for the test. Besides, in my opinion, the test/certificate is incidental, the real value is in the knowledge and skills gained.
