A friend spotted this F1 that is up for auction shortly. Looks pretty nice to me. Just a couple of questions- the Conti silencer looks mostly like mine's but the end looks much less restrictive, was that an option/aftermarket version? Also, does anyone recognise the tyres? I though BT45s were the only thing available in F1 sizes, it's good to see there is something else out there.

The Conti looks correct. I do believe one had to get that (competitizione?) silencer as an option—I do not think they came on the standard F1 from the factory.

On your tire question......based on the tread pattern, looks like Pirelli Sport Demons......
