Inspiration_ Initially bought SX150 frame with matching, and bare, engine casing. Wanted cheap, sporty, fun bike, with minimal chrome, and always like the look of an SX, with GP panels. Aimed to keep it as light as possible so no toolbox, and fibreglass parts.

Performance_ still running in.

Anything else_ took about 12 to 18 months whilst I picked up bits. It’s a classic “bitsa” really. There’s plenty of Series 2, Spanish, and GP parts in there if you look closely enough. With the exception of the paint, everything built by me, with technical assistance from friends on the LCGB forum!
