This bus is mean!

Recently Bexleyheath have plugged a few of their B9TLs into TopoDyn power mode. One of them being WVL421. This one is in Power mode and because of said reason is super powerful, can get to speed easily and is very reactive to when driver wants to apply more power to the bus. Which happens plenty in this video with lots of downshifts and topodyn used.
Enjoy !
