Is there a certain temperature which is not recommended for riding (for the bike). We don't seem to be getting many days under 35 degrees celsius here at the moment, but i'm busting for a ride. On the odd occasion where my body thinks it can handle the heat, will it harm my 02 426 riding it in this heat provided the usual maintenance (oil, coolent etc) has been kept up to date. Most of the riding is in relatively open terrain. Not too much tight stuff.
