The gates belt is better then the mallosi,It is designed for street use,ie...thousands of heat and cool cycles,the mallosi is a racing belt,it is designed to get"sticky"as it gets hot for more grip during racing,problem is,being kevalar it has not flex or stretch and will not survive street use,it is for racing,1/8 mile at a time,If you ask around,you will see that everybody that puts the mallosi on ends up walking home at one time with no warning either,But personally,I think mallosi sucks,the belts break,the variators wear out the guides very fast,their air cooled cylinders have wrist pin rattle at 7-8 k rpm's,I don't like mallosi and now their is no importer for mallosi,rosell imports is out of bussiness and took customers money and gave no parts over the past 2 months.I wouldn't bother,polini,metrakit,stage 6 are the companys for street worthy performance parts.
