The 177 Kit for the Yahama Majesty Motor is the performance kit for a normally somewhat weak motor. In combination with a longer transmission and a multivar, the 177 Kit perks up the sorry original 95 km/h top speed. Another quality kit is the 140 ccm aluminum kit for the old 4-tact motor from Piaggio ET4 or Hexagon 125 LX.
This was the first kit available for 4-tact motors. Watch this kit pump up a wimpy 8,3 hp ET4 to 20% more performance; when you're finished you'll have 10 horses under your saddle. Gone are the days of dragging along at 90 km/h with everyone overtaking you. Let them eat your dust for a change while you cruise along at 105-110 km/h. You can depend on needing less oil with your "old" Piaggio motor, that alone is be reason enough to installi the 177 kit. Test Scooter & Sport "plus 26%".
Also new on the market are the 187cc and 209 cc cylinders for either the air cooled or water cooled Piaggio Leader motors. The manufacturer is months, if not years, ahead of everyone else with this new kit. A real power me up for Leader motors. Turns 4-tact scooters into real competition for their 2-tact cousins.
