Got a super high mileage derbi variant sport last spring. Rode it around stock for a few months. It actually did like 42mph bone stock and clapped. Not bad. Most of the Plastics are cracked or broken, The stock pipe was rattling apart ect. Also the headlight was extremely dim and only worked sometimes. Aside from all that I fell in love with it immediately.
I’m still very new to the flatreed, but it’s super forgiving.. the engine wheels and frame are super robust. Last fall I got the 50cc zen, a 19phbg /intake, the gila 50 and threw a one way bearing in the clutch.. Slapped those on the bike without a rebuild. It’s the fastest loudest moped I’ve owned. i love it. The original piston was roasted! I also scored a ds50 parts bike about 45 min away, for 250. got a lot of good parts off that.
With the second engine I got from the ds50 I’m going to build this vintage metra 65. From what I’ve gathered it’s sort of odd ball. Looking for a 65 head. 77’ says they have one in stock but I’m afraid to order from them..
I’d love to hear from any derb lords.. especially about this metrakit.
