Lambretta Cylinder head, 125-250, square head, without cowlings, centre plug, Race-Tour MB
This is our original special heat treated aluminum cast oversized center plug head.
The biggest and best cooling head on the market.
It is designed to fit without a head cowl. Originally these heads were made for racing and sprinting but over the years have been used many times on high powered road engines with no ill effect because the size of the head the engine cools better. These are pre-machined with stud holes and center plug to suit 200 large block casings. You can take this head fully machined to suit or take these part machined and you can finish off the combustion chamber and squish your self (this will be a reduced price)
These heads are machined to order so please confirm specification when you order
- we need to know the piston used
- and diameter
- any other another pointers you require

- MRB have been making special cylinder heads for many years.
- This development has produced the strongest heads available.
- Always check squish clearances upon assembly.
- Always make sure the head is centralised to the piston.
- Always torque the head bolts to 18-20 lbs ft.
- Re-torque the head nuts at 500-600 miles
- Always use MRB special cylinder stud, nut and washer kits.
- Access to the plug can be tricky making this head not 100% practical for a road going scooter, TOP TIP remove the rear shocker to get easier access with a socket and extension bar from underneath.
