Hi all. The new bike (2012 z1000) has the tiniest space for storage. My old bike (2003 zx9) had enough space for my phone,wallet. can of tyre puncture spray (dont know if they are any good)...and the standard onboard tool kit.. The new bike fits the tool kit..the rego plackarde (still to find a good home for it) and my wallet and that is it.. Because of this limited space I am thinking about getting a small back pack.. The question I would like to get some thoughts on is: What are the essentials to take along while riding..I realises it may depend on the length of the ride..but just want to get some feedback on this subject.. For example..do I really need the tool kit?.. I also realise that there will be a plethora of amussing replies about what is "must have" so..bring it on!
