You're right. The CB125 is a thumper, just a small thumper.
They can be great little bikes (they can also be very fussy when things start to get worn). I had one for a couple of years (had to sell it when I moved to an apartment block a year back).
My "adventures" are recorded in the reports in my signature. I miss that bike like crazy - it was so light and simple to ride, just a blast of fun.
