As you can see in the tech drawing, the Classic tm weights and
throttle locks are 1.999" long. With straight bars like drag
bars or MX bars, this means a nearly 4" increase in width.
However, the more the bar ends are angled toward the rider, the
less the width goes up. For instance, a 30 degree pullback on
the grips will grow just less than 3.5" in total width with the
addition of weights or a throttle lock.
