Motorcycle bar end sliders are designed specifically to replace the OEM handlebar end weights on bikes and protect our handgrip from damage.
These are typically including a removable puck and the protective guards are also completely replaceable in the event of a drop or slide.
Bar ends extend our handlebar, and allow us to move our hands more forward, this lowers the center of gravity at the same time. When we go uphill bar will make it a little bit easier and will increase leverage.
Also, the weight applied on the ends of the handle is there to make sure that they make sure the bike's handlebar does not vibrate due to the resonance that occurs right from the moment when the engine of the motorbike starts.
And it is considered quite essential and comfortable to use bar end sliders as they provide a comfortable grip and less pressure when driving for a long time on a trip.
