Can anyone advise please - my RC390 is due for its first 600 mile service which is basically an oil change, fault diagnostics test and chain check and the dealer I bought the bike from; Fowlers of Bristol are quoting £194 plus VAT!!! I asked several times for confirmation from them that if I use a non KTM dealer, would this invalidate the two year warranty? I was advised by three different representatives from Fowlers that provided genuine KTM replacement parts are used it will NOT invalidate the warranty, but I cannot get this in writing. I asked Fowlers to get it in writing from KTM and they got back to me saying KTM would not put this in writing but by law are bound to allow another competent engineer to do do the service work. The second service is 4.600 miles so this could be an expensive love affair. Has anybody got any advice they could add please? I am nervous from rumours of reliability of KTM off road bikes that my garage engineer warned me off and he rides dirt bikes.
