Footpeg — Stark Future
2026
Titanium footpeg redesign for the Stark Varg Skugga: a longer, lighter and structurally validated off-road component developed through parametric CAD, topology optimisation, FEA and additive-manufacturing planning.
Fixed interface, longer support, controlled geometry.
A parametric skeleton controls the critical dimensions: 160 mm length, 50 mm width, 5° inward tilt and 85° relative to the side plane of the motorcycle. The CAD work resolves the transition from the bike interface to a longer, lighter support surface.
The rib pattern comes from the load path.
Two load cases mapped the structural behaviour: 5 kN at two-thirds of the support plus 5 kN frontal load; and 3 kN at one-third and two-thirds plus the same frontal load. Both studies pointed to a diagonal main rib with secondary reinforcement near the interface and tip. The final geometry reaches the minimum safety factor target of 1. Maximum von Mises stress appears around the interface and decreases through the rib network. Maximum displacement is located at the far tip and remains controlled at 3.43 mm.
Print orientation, build plate and JIG close the loop.
Bambu Studio was used for rapid orientation studies, then nTop for support generation and build-volume distribution. The final orientation is 40° in X and 27° in Y, with an estimated 22.3 g of titanium supports per part. The JIG fixes the printed part for repeatable machining of the spring-hole interface.
The final proposal is not only a lighter part: it is a complete design-to-manufacture workflow. The project links a specific use case, a parametric modelling strategy, topology-driven material removal, structural validation and a production-oriented additive-manufacturing setup.
