The garage originally said it was because I was thrashing it after the previous owner was gentle with it, until I pointed out the GPS linked camera fitted to the front of the bike (all the evidence police would need) then they said it was running dry, but now I work in haulage I've learned the value of pre-ride checks and track the oil level and it was above the low line, so now they think it was the timing belt slipped causing the engine to go out of balance and self destruct. To be fair to them they bent over backwards to look after me, giving me £1000 for a written of 96 zzr11 (I paid 1350 back of the garage number). I wanted to get an er5 they had but they refused to sell it to me as they said it wouldn't cope with the miles I do (80 a day on motorways).
