Product description
DRT have also decided to address the subject of all the remaining diagonally cut gears out there and have taller gearing now available for small frame motor setups with a cubic capacity of between 50 and 75cc. According to the cylinder used, an increase in top-speed of up to 10km/h (6mph) is possible. The primary drive cogs with 16 teeth fit onto scooter motors with an original cog teeth combination of either 14/69 or 15/69. Due to their exact fit in combination with the original clutch cogs you can be sure of reliable performance over a long period. Before you order a replacement cog check the size or number of teeth on the original item. The cog with 17 teeth is an excellent supplement to the cog teeth ratio of 16/68 from the V50 Special. The cog with 19 teeth is suitable for the original cog teeth ratio of 18/67 which was used in the VESPA 50/N/L/R/S/Special/S
