Expansion bolt Special 690 for Big-Bore Engine KTM 690 with high tensile strength
why change the original bolts?
The original KTM expansions bolt weaken quickly after enging-tuning. The bolts are overstretched in the longitudinal extension of the cylinder and so lose their pretension. The consequences are usually ruined head gaskets and thereby conditionally warped cylinder heads. Here our new expansion bolt can help. With a tensile strength of more than 1,200 N / m² and made of heat-treated steel with a strength class of 12.9, the operational safety is guaranteed.
