the 'spazzos' as they are known as are great.. have had 2 sets on my r1 on account of a mastercylinder change and never had any issues.. with both sets although i have to note i've had to buff and bore out where the lever meets the piston on the m/c as they were putting a bit of pressure on the piston which i wasn't happy with ( have had a few incidents before with front wheel locking up at speed, that i always make sure is completely avoided now lol ), i don't mind performing such minor modifications in the name of safety and neither compromised the structural integrity of the lever.. will be ording a set up for the millono in the near future.. and if you tally it up i'll have had 3 sets of 'spazzos' for the price of 1 set of pazzo levers..
