It's true... we use SLA parts on the actual race bikes! After using SLAs for verifying designs for the production Enertia before investing in hard tooling, we started experimenting with using SLAs as functional parts on the No.11 Enertia TTR race bike during the TT in 2009. If you take a good look at the photos from that event you'll notice that the no.11 bike had a different tail design to that of the no.26. The part held up beautifully to the rigors of the TT track, so we expanded the usage of the materials on the Empulse RR to the main fairing, side fairings, and undertray.
