I received a gift from my brother that might come in handy for the buggy (that wasn't it's intention, but it was the first thing I thought of).
It's a wide adjustable wrench that is only 6" long and is big enough to fit my axle bolts on the xr. You wouldn't have the leverage of a normal
wrench obviously, but it's light, portable, and seems to be very well made.
My brother just got those same knipex tools and loves them. I noticed they are made in Germany and if you get your hands on one, you can tell they
are a very well made tool with attention to detail.
Working in an office environment for many years I was always envious of the cool tool kits that the copier repairmen carried to the job site. So I
finally bought myself an empty attache style tool box & filled it with what? Knipex tools of course. So nicely done the tools are almost like
fine jewerly for a man. Klein is another high end brand if you wish to stay with made in U.S.A. When I bought a vintage buggy I enjoyed replacing
all the fasteners with stainless steel socket head cap screws & making a little hex key tool kit to carry along.
