I was on nights last night so not my first choice going out today, but it had to be done, Roads were melting and my rad has suffered due to tarmac on the chippings. I am making a rad guard before going out again.
I have had more issues with cooling than stones but, they have just stuck about 4 miles of loose chippings before my route out, I even had them hitting my visor from the front tyre.
The main reason I fitted the front ‘Fenda Extenda’ was to keep more stuff off the radiator. It’s got a guard on but better to reduce the amount of stuff it has to deal with
