Aprilia RS660 & L74 Quick Change Kit - Rear Wheel Swap

Our 2022 Aprilia RS660 Trofeo has been fitted with an L74 Quick Change Kit. It is a great bit of kit! See our other L74 video for a closer look of the kit with the rear wheel removed.

is there a reason why the threads are backwards? i've seen this before, is it so the tire spinning tries to tighten it?

[@TwoDavesRacing]

I’m not sure to be honest.
Cars and trucks stopped using lefthand threads on wheels as it made little difference regarding torque transfer (ie bolts coming loose).
Perhaps it’s easier to machine with that type of thread 🤷‍♂️👍

This type of threads are more commonly used in places where there's alot of spinning i.e inside the engine components like camshafts or radiator fans on cars.
But It's a safety feature that significantly lowers the chances of the bolt coming loose since the wheel is spinning in the opposite direction of the treads. They engineered it like this coz it would be catastrophic for both the bike and rider if the bolt came loose since it's all that's holding the rear wheel in place. This is also why it's important to use the right torque specs on your bolts and nuts. In some cases it could be the difference between life and de*th!
