Jarrod ‘Jack’ Frost Clocks 274.9mph at Elvington
Coverage from MCN tells us that Frosts’s turbo-charged Suzuki Hayabusa whipped up an insane 274.926mph st Elvington – a full 3.961 units faster than the course record for ex-TT adrenaline junkie aficionado Guy Martin.
“I’ve hit 269.9mph before on the standing mile loads of times,” comments Frost easily.
“That 270mph barrier was like a brick wall. It was so frustrating, and I was having a bit of a laugh with Guy about it the other day because I’ve done 269, actually 269.9 probably six times and just never broken that 270 barrier on the standing mile.”
The story can be summarized thus: Frost was stuck at 269, tinkered a bit, locked down 269.98, the bike was threatened with retirement to the van, boost and sprocketry were tweaked, and suddenly, 270.7 hit.
