Top Racing Center/compression Springs (set +31%/+47%/+57%), Honda / Gilera / Kymco / Peugeot / Piaggio

set of three compression springs from the renowned Portuguese company Top Racing. The set includes springs in three hardnesses, easily color-coded: +31% yellow, +47% red, and +57% blue. The torque-correcting spring has multiple functions. Choosing a harder spring tightens the belt between the discs, allowing it to transmit more torque without slipping. Using a weaker spring, the degree of compression is better, but there's a greater risk of belt slippage. Spring hardness also indirectly affects engine speed. The optimal solution is to purchase several springs with different hardnesses and select the appropriate one.
