Sed57 - Ouch, sorry to hear about that! This is the one Achilles heel of the GT250 Comet, its weight for its engine size. If it'd been lighter, you could have managed it better and also the pick up and fuel economy of the Comet would be better too. On the other hand, it is a full-sized bike (same size as the Hyosung GT650), so the transition from a learner's bike to a full license bike will be minimal...

I found a few bits off Trade Me for my Comet when it had a similar tumble to yours, e.g. clutch lever and gear shift lever. Cheap prices for new too...
