Re: when and where
 

Definitely can get a bit 'busy' in a full pack going round the first corner of any start - not unusual in a regulated stock class - and at times I have seen (this season) a 9 bike at Oulton (oil) and a 8 bike pile up at Brands (Cold tyres) in minitwin races. Not sure if they are any worse than any other series though? Our own tally is 5 major offs this year, one crushed knee joint, one engine rebuild + gearbox, lots of other successful rides, some trophies and great fun. Cracking!
