The cores are made by a company who do most of the racing rads for Cars and Bikes. The header tanks are made in house.
Curved ones are more than twice as much to make.
They are re-assuringly expensive but you gets what ya pays for.
A Suzuki rad for the RGV with a bit of extra capacity and buying cheaply in Europe is still 800 euro's..........£540
Thermostats are ok........on a road bike but struggle in race and track conditions by being fairly slow to react so the temp rises and falls a lot. A top quality rad like these will maintain better stabilty at your optimum temp. You don't actually need double core on your NSR if you go for a good quality core. By shrinking the header tanks we have got a 20% bigger and more efficient core so overall the rad is a similar external size needing no mods to the bike. Get the rad too close to an exhaust pipe/other heat source and you defeat the object.
It's an exlusive radiator. Once you've got your mini-indicators pipes and rear-sets what next
Was not planning on an NSR one but if there is interest let me know. Thanks to andy for showing the RS125 one.
