Made from Grade 5 (GR5) titanium this engine mounting bolt reduces the weight of your YZF-R1 by over 4 oz, or 1/4 lb, with a weight of only 158g. 

Precision machined and polished to a near mirror finish, these highly specialized shafts were produced for our MotoAmerica Superbike program, but we are now offering them to our customers as well. Our upper engine mount bolt is available as well, or the kit can be purchased as a pair.
