caps, they aren't an entirely bad thing. Heavy but not the heaviest, I think my '69 TS250 may tip the scales on it and pretty sure a stock XT500 would weigh much the same
..lots! Apart from the weight factor it's not a hidiously bad thing. It won't win races but it's fun , reliable, nobody much fights over the bits and all the TM400 goodies will bolt straight on if you so desire a hotty. The weight must be in the chassis as the rest is basically of TM400 design..never really compared the weight of the 2 but you can lighten it substancially if it scares you like it did me..actually, it still does!
a good reliable thing but they need a serious diet.
