Looks great - I fitted the SW Motech one very similar not as much up front and shorter on the base, however, what I can say is that during winter no problems but now it is summer the last two rides 35-38 degrees C I have found my left boot is getting cooked, the OEM bits on the left vent the heat directly to the toe and the top of shin, I am going to have a look this weekend to see if they need to stay I am thinking of leaving them off.
The right side not as bad as it does not have the same vents and the top one is closed off.
My only concern is that the left one does seem to protect hoses etc., possible test I am thinking of doing is tapeing up the small toe level vent on the left from the inside and see if that makes a difference.
As well worth the heat in winter
keeps the boots warm just not wanted in summer.
