VE10900 BGM PRO 177cc CYLINDER KIT compatible with ELECTRIC START & KICKSTART MODELS - VESPA PX125-150, LML 125 2 stroke. The bgm PRO 177 cylinder kit comes with a ceramic plated alloy barrel with 63mm bore. The piston has two 1 mm rings and high content of silicium. There are four main transfer ports and two boostports. The cylinder kit is designed to give lots of torque from low down and a very broad power band. The port timings with a 57 mm crank are 118° transfer timing and 171° exhaust timing. The kit is easy to fit and a Plug & Play solution that works out of the box. With a SI carb and the bgm Big Box Touring the power at the rear wheel is 15 hp and the torque 17 – 19 Nm. Higher power outputs are easy to obtain and 25 hp shouldn’t be a problem. Low fuel consumption and high cruising range are further extras. Capacity 57 mm stroke 177 cc, 60 mm stroke 187 cc Recommended squish clearance 0.8 – 1.2 mm The transfer ports at the base are casted with a gate. This is matching the ports at the casings perfectly. The gate can easily be grinded away to use the complete cross section of the transfers. The cylinder head is fully CNC machined from billet alloy with 4 mm recess. The recess is for centralizing and sealing. In the centre at the top of the head is a thread, if you want to use a temperature gauge. UPSHOT: Perfect allround kit that is easy to fit and setup. Gives power and torque low down, broad power band, low fuel consumption and an unbeatable value for money! ONE TO WATCH: Can’t be used out of the box on engines with electric start or electric start flywheels. In this case the toothed ring on the flywheel has to been taken off. Or a flywheel without this has to be fitted. Cross reference BGM1770NE.
