When I had my TZ I can say for certain that it was the same size, but maybe 2/3rds the weight - that's why the thing goes crazy when in play. KTM450 has a TZ at the moment (as I'm sure some others do) - can someone take theirs out and weigh and measure it (assuming it's an original ceramic one).
I'll weigh my powerball when I get a chance, working the next few days
