KTM 690 SMC SIGMA PERFORMANCE SLIPPER CLUTCH
Six ramp, wet type. Hard anodised in grey; Clutch centre only. Uses standard clutch plates and springs.
Sigma slipper clutches are designed to allow easier downshifting on the road or track. Originally a pure race accessory our slipper clutches smooth gear changes for skilled riders and beginners alike by automatically and seamlessly disengaging the clutch whenever engine braking or rear wheel hop becomes excessive.
In racing SIGMA slipper clutches have proven themselves to be a reliable and effective addition to many a racing teams armoury. On their very first outing in a Ducati back in 1998 they won a World Superbike support race at Donington and in 2004 at Brands Hatch won their very first British Supersport race on Jay Vincent's Padgett's CBR 600. Since then they have won many BSB Supersport races and championships and a bunch of TT’s and North West 200 races.
