I have just ordered the Gilles rear axle nut and top yoke nut. The top yoke nut is unique in design and has a unique locking mechanism to hold in place. The yoke nut is alloy and will be anodised black to suit the bikes colour scheme. The rear axle nut comes in the same unique design but made out of titanium and weighs in at a super light 20 grams. This is 15 grams lighter than my existing titanium nut! I can also use this nut for my swingarm bolt to further reduce the weight.
Well I doubt I will ever be brave enough to buy a conversion like this but saw these and the think they look amazing. I find that a great deal of headlight conversion often look tacky and dread it when I hear of angel or demon eyes. These however seem tasteful and do seem to suit the lines of the bike.
