When designing the BOTT M210, we have tried to use solutions that facilitate the work of the mechanics. The most important aspect of a race bike is beeing fast on the track, but it is also very important that the mechanics can work on the bike quickly and safely. Good race bikes are full of small details that can greatly facilitate the work inside of the box. In that sense I feel very fortunate to work closely with Jose Contreras, who has several years of experience in Motogp and now we can implement much of that experience in our Moto2.
Let’s see some of the BOTT M210 detais, in this case in the rear wheel axle area.
The head of the rear wheel shaft has a bell that helps to center the spanner cup. Ducati uses this solution in their MotoGP bikes.
The piece that serves to clamp the brake caliper is also used to hold the rear wheel speed sensor. This sensor reads impulses from a sheetmetal part that gives 24 signals per each wheel revolution. The cable from the sensor makes a loop shape to avoid tension when changing the wheelbase.
The sliders used to tighten the chain have a small platform (not seen in these pictures because they are on the inner face) that keep the wheel in position so that when we remove the wheel shaft, the wheel keeps in place. This is a great help when you change the wheel, you let it fall between the two arms of the swingarm and it is always perfectly aligned with the sliders so you only have to worry about pushing the shaft.
The anchor for the bike stand is located behind the swingarm, in that way you have more room to work in the brake caliper if necessary.
The quick connector of the rear brake line has a black rubber around it to avoid friction with the swingarm.
On the left side of the bike you can see that the nut is screwed to the slider, in that way we don’t need to worry about holding it when we remove the wheel axle. You can also see that the shaft is tapered to facilitate it’s placement on the wheel.
Many of these ideas come from endurance bikes and nowadays are used by the best road racing bikes because they allow to work more quickly and safely in the qualifying sessions.
