If you go over circuits 300 km / h on a bike 230 CV, you better go well protected just in case the floor… Is not?
Por fortuna, today the finest materials and latest technologies are used in each leathers, thus offering the greatest degree of protection possible.
It is quite hard for gravity riders being injured or even killed because of the monkeys, in fact, the most fatal accidents in recent years have been the result of bad luck as the Italian rider Marco Simoncelli.
The monkeys are tailored to the pilot to achieve the best performance, but also to ensure that if dropped, all protections remain in place. So, at impact, protections do not jump or move. Manufacturers measure the pilots during the pre-season and adjusted to the millimeter monkeys.
The usual weight is between the 4 and 5 kilograms and in it there are protections on the elbows, shoulders and knees. What protects quite. Monkey lining can be removed for easy wash.
As for how to sew, monkeys are constructed with different panels. If you use double stitch, It does this twice in the most challenging areas. Inside, also carries double stitch all, as the outer. Also, using special threads which remain even when broken structure.
The best quality leather is chosen. In most cases it is cow, but also use kangaroo. The first is used because it resists abrasion well, typically has a thickness of 1,2 a 1,4 mm.
Being the good quality leather is very resistant, so much endures abrasion.
Installed thermoplastic protection in the most critical areas of the body. To this are molds having two densities, harder in the center and less abroad, and a coating and a protective gel below.
The idea of these special protections on shoulders, elbows and knees may help dissipate impact energy and extends over a larger area. So the energy received is less protection. The first contact with the asphalt is usually very fast and hence try to reduce friction. When the pilot is slipping, the impact energy is dissipated.
The slide is elbow protection, but put an extra slash if the pilot chute elbow. It does not everyone, depends on driving style. Marc Márquez is the pilot who uses this technique more clearly, and there are now few drivers who also do.
Also used an airbag system that protects the upper body (Hans similar to Formula 1). The areas that stretch are very important when the airbag is triggered, for about four or five inches is usually inflated. So the monkey has to expand. Most pilots used as a safety airbag.
It is important that the rider does not suffer so much heat that the monkey is very ventilated in the front. The aerodynamics on the bike helps it, but that all, Monkeys are designed to direct the air into, to the body of the pilot.
Once the air is in, must leave, so in the back of the monkey holes are slightly higher, down to the legs. Build a positive airflow through Monkey. The same is true of gloves. All this helps to keep the pilot cool and to have the physical form.
The hydration pouch is hump Monkey. Usually there is only a 200 the 300 milliliters of fluid because one of the problems is the weight of the monkey and everyone wants it to be as light as possible.
MotoGP riders are not much dehydrated in a career, although they are dry mouth and this is awkward. So drink it's a relief. The bag is on the hump and have a duct leading to the town, where the pilot just has to suck drinking.
