The Vario is the heart of every automatic scooter's driveline. That's the reason why big time manufactureres like Malossi and Polini pour all their technical know how into putting optimal tuning varios on the market that top the normal serial production product. One of the biggest drawbacks with original varios is that their manufacturers have to keep material costs down, which lowers quality. A second reason; the increasingly tougher noise regulations which force manufacturers to construct varios that poop out when you need power in the middle rpm's, all at the cost of traction and acceleration. The Multivar from Malossi as well as the Maxi Speed-Control from Polini are (highly successful) answers to your power problems. Designed with newly calculated roller slide bars, self lubricating sockets of vitrified steel and crowned with a hub of highest quality steel alloy with a slide face of ground and polished hardened chrome. The half disc is made of silica-aluminium alloy, milled by high precision NC machines with a diamond polish for the finishing touch. Power packed precision engineering which will reduce your performance loss by 30%! You won't have to lubricate these high-strength calibrated vario rolls due to their manufacture of durable Teflon composition. Both tuning varios offer you high end technics at a very reasonable price (compared to original replacements parts...). Installation of a tuning vario is an absolute must for all 2-tact and 4-tact pilots who want to improve their automatic's power and performance. An extra bonus: makes your engine run quieter.
