I haven’t weighed the 507 but did get a chance to weigh the 508 Nassau, among some other new body pieces. See below…
Nassau
- KG 508 with stickers = 1008g
- OTK M7 Nassau with stickers = 1100g
Side pods
- KG 506 with stickers and nerf bars = 2100g
- KG 507 with stickers and nerf bars = 1800g
- OTK M10 with stickers and nerf bars =1776g
Can also confirm the KG 508 Nassau panel is compatible with 506 and OTK M7 top brackets.
The KG C3 rear bumper also fits OTK
