Thanks will. As it was my first bike that was less than 50 yrs old I did wonder if that was the standard compound from which all modern tyres were made.
The supplying Honda dealer was useless - (all stainless steel clothing racks and posh polo shirts). It was returned after the first service with the underpan missing, three of the four bolts holding the stand hadn't been replaced, the stop light didn't work, the clutch adjustment meant I couldn't select neutral when stationary with the engine running and the oil was more than half a pint over-filled.
They collected it and fixed it and sent me a £25 voucher against the next service I would have there. AS IF!
I emailed my disgust to the VP Europe with photos and received a 'How did we do?' questionnaire back. Needless to say I didn't reply. I part-exchanged the bike for a Chinese 250 which has been faultless for 3 years and so is the dealer and his old school 'greasy rag' workshop. (Haywards of Cambridge).
