Here is a value priced 12.5 liter/3.3 gallon Lambretta long range fuel tank with a cutaway on both the left and right sides so you can use it with TS1/Imola/RB/SS kits or on standard left exit carburetor setups. Comes in primered mild steel so you can paint it to match.
Replaces your stock air box so you will need to run a pod filter on your carb unless you have a Serveta that uses the combined airbox/toolbox. Comes complete with tank straps and fits S1-S3 models. Use your existing rubber tank strap buffers and trunnions when installing.
Great on any stock or tuned Lambretta.
Don't forget to grab a fuel tap while your at it.
*This value priced option comes with the inside oiled so it doesn't rust. You will need to clean it out with some mineral spirits or kerosene and probably some gas before fitting it*
