Based on insights from Mat Oxley & Australian Motorcycle News (Valencia Test)
The KTM RC16 was spotted at the Valencia test sporting significant ergonomic and aerodynamic updates. The goal is clear: reduce physical strain on the riders and manage the brutal braking forces of modern MotoGP.
1. The Yellow Arrow: Extended Tank Support (Leg Lock)
The carbon fiber component pointed out by the arrow is a braking support extender.
- The Problem: Modern MotoGP bikes generate over 2G of force under braking. The “wings” on the front of the bike create massive downforce, pushing the front tire into the ground, but this also throws the rider’s weight violently forward.
- The Solution: This new “tank wing” widens the top of the fuel tank cover significantly. It creates a hooked ledge that allows the rider (like Pedro Acosta or Brad Binder) to physically “lock” their outside knee under the tank during heavy braking.
- The Benefit: By locking their legs, riders can take the weight off their arms. If a rider has to support their body weight with their arms during braking, they cannot steer delicately, and they suffer from arm pump. This part transfers the braking force into the rider’s legs and core, leaving their hands relaxed for throttle and brake finesse.
2. The Yellow Circle: Downwash Vents (“Shark Gills”)
The vents on the side fairing are part of a revised ground-effect aero package.
- Airflow Management: These louvers (vents) are designed to take high-pressure air from the radiator and engine area and eject it downwards and backwards.
- The “Air Curtain”: Mat Oxley often notes that these designs help create a seal or “curtain” of fast-moving air along the bottom side of the fairing. This helps prevent dirty, turbulent air from getting under the bike, which maximizes the ground effect (suction) created by the lower fairing spoon.
- Cooling: Additionally, they help extract heat from the engine more efficiently, preventing the bike from overheating in the wake of other bikes.
