Sorry if this seems like a basic question, I'm still in the process of buying the tools I need for my bike. Okies, so I bought my VTR250 a Christmas present, a new handle bar which is a bit wider and lower. So my problem now is, removing the hex bolts (sorry if that's the wrong names) that hold the bar down. I have a set of allen keys, I think they are also called hex wrenches. Looks like this: And these are the bolts I'm trying to get off: I can't get enough leverage with the allen key I have. There has to be a better tool out there for the job!
