Just measured mine today on a set of longacre cross weights.
1075kg
Forgot the cross weights, but front rear is very close to 51:49 and 50:50 side with me sitting in it.
The measured weight is with 1/4 tank, spare, mild steel rollbar, stripped interior, 15x8.5 watanabes and street tyres, racing buckets, and a triple webered L24.
I havent tried too hard in the weight loss department, so there's plenty of room for improvement!
