Being something of a Kawasaki fan, it was perhaps inevitable that Cumbrian Martin Forster would acquire a GPX750 to contest the Superstock class. Third last year in the CRMC senior Production class aboard a GPZ750 and on a GPZ550 before that in Junior Production, Martin is already making waves in Superstock aboard his nicely run-in 50,000 mile GPX.
“It’s fast, and already competitive against the GSX-RS, FZS andvfrs,” smiles Martin. “And it’ll only get better as I get used to it. I bought it from a bloke in Hull [Chilly Hill, whose trick XJ550 has previously starred in
PS – JM] for £750. He’d been using it as a winter hack. Other than service it, fit a Hagon shock and stickyavon tyres I haven’t done much to it. It still wears its original bodywork, and I’ve stiffened up the forks with heavier oil and spacers – I’ve got Hagon progressive springs on the way but it feels really good as it is so I might just leave it.”
Martin was using the original shock at Pembrey, where he scored a sixth. It was overheating at thewelsh track due to a duff radiator fan, an issue he’s since fixed.and the fibreglassed bellypan and turkey basting tray makes an ingenious oil catch tray…
“I did put it on a dyno before Pembrey, just to check it was OK. It made 106bhp on the first run even though it was really lean. We went from 112 mains to 124s, and power’s up since, too. I’m really enjoying riding it. I just wish the weather would improve. Fingers crossed for Oulton.”
