If the extra cost is not an issue I would get the Wave with a bit extender and a bit set that can be used on your motorcycle. Extender for the hard to reach nuts and most probably you will need Torx/Allen bits I assume. What mods you plan on doing? Best bet is to think of the things that can go wrong and if the tools you plan on carrying can be useful. Sometimes only dedicated tools will do the job.If you already carry a motorcycle specific tool set and looking for a MT for general use I would go with the Signal. Just my opinion
on the Crunch but, having both Signal and Wave, I'd call dibs on the Wave. Cheaper, smaller chassis/more compact, as easy to modify, but can have more tools. I've used the scissors for cutting patches to size, duct tape and zip ties for impromptu repairs, and for grooming tasks myself; the file for deburring the handlebar's ends after a crash for comfort, all while on bike rides (although the bicycle type and not motor bike!!!). Just an idea and my 2 cents; either one will be a great companion.
The Wave...can have more tools.
Motorcycle and Bicycle. I mountain bike a lot and wanted something handy to have along on those rides as well. I really appreciate the input on this topic.
