This is an old revision of the document!
The radiator is one of those areas where Aprilia seems to have cut a few corners. But something worth noting is that the bikes will go a very long way with little or no fluid.
This has been tested (mainly by) Dobbi in such places as Morocco, and most of the UK. Also by YTC1 in such places as Mongolia and Russia.
The radiator fins are easily damaged, but can be repaired with our old friend epoxy resin (for small leaks). Otherwise it is possible to get the core repaired. East End Radiators will do a check and repair service by post.
Adding a Radiator Stone Guard is highly recommended.
The fixing of the radiator overly hang it from the two fixings at the top rather than seat it on the fixing below it. This causes a telltale breaking of a core at the rear of the radiator close to the upper fixing point near to the expansion tank.
Many report that adding a thick washer underneath the bottom fixing point pushes teh rad up enough to stop these stesses.
