Rubber Lever End Thingies

Followers of Moto GP may have noticed that when Marc Marquez's bikes are in the pits, towels are thrown over both clip-ons, even on the quickest pit stops. The explanation had always been that the grips were super-sticky and it prevented dust and debris from settling on them.
However, drone spy pictures from last year's Qatar practice sessions recently posted on a well-known Russian site showed otherwise. The pics have since been removed, but high magnification had shown that both levers had RLETs on them.
Both RLETs had been coated with a low-friction silver silicone paint to make them match the levers, but they were unmistakable. The only other difference was that they were beveled on the bottom for ground clearance, so they were for a specific side.
This was later confirmed by the race team member in charge of controls in 2015, who was fired after installing the RLETs on the wrong sides, causing a reduction in ground clearance and possibly resulting in a crash that eventually cost them the championship, although Marquez never blamed him openly.
More recent spy pics from late last season showed as a result that both Yamaha and Ducati were testing them but with no success, causing some high-speed stability issues. Apparently they work well only on Hondas. But we knew that.
