Malossi Contrast Spring (yellow, reinforced) – clean tuning for your 400cc Maxi-Scooter

With the reinforced yellow contrast spring from Malossi, you get an important setup part for the variator tuning. Especially for the Suzuki Burgman 400, the right combination of contrast spring, variator weights, and clutch springs can determine whether your drive pulls through cleanly or unnecessarily leaves performance on the table.

If your V-belt slips, it is a clear sign: in that case, you should definitely use a stiffer contrast spring. At the same time, it applies: too stiff can also have a negative effect on power output. The art therefore lies in the correct overall setup – especially if you want your Suzuki AN 400 Burgman to be perfectly tuned.

If you are stuck while tuning your scooter, it is best to check a suitable online community – almost every conceivable combination of variator weights, clutch springs, and contrast/counter-pressure springs has already been tried out there.
