Cracking effort, but there’s easily 10-15 seconds to come out of that lap without modifying the bike. He missed quite a few apexes, got held up 2 or 3 times, and by the sounds of things the bike is a bit short geared.
Just been on his website, the bike is a 2005 Yamaha R1. Not a slow bike by any means, but litre bikes have moved on performance wise since 2005. His has been modified to lose weight and handle better, but the engine is still stock. “Stock” means about 150bhp or so, but put him on a stock BMW S1000RR even with 193bhp, and things change.
If someone gave him a budget (or even better a much faster bike), he will easily go under 7 minutes.
