Bikes must always be maintained by a qualified mechanic, so while you are riding the experience remains enjoyable and fun. But unexpected situations are inevitable, a broken clutch cable or a punctured tyre can ruin the whole ride out. To avoid these sort of situations you must carry a Bike Tool Kit while riding, and why not make it an experience of the day out as well, repairing your much loved bike. Now a days almost all good companies offer very good quality tool kits that can be kept under the bike seats and you can use them during your journeys.
Funkymoto recommends the Oxford Biker Tool Kit or the Viper Moto Puncture Repair Kit.
Be safe and have fun.
