i used auctmarts on my 954. ive been pretty happy with them. of course they arent quite oem quality. ill say i expected that last statement to be the case and im still pleased to say that auctmarts exceeded my expectations for quality. little rough around the edges concerning paint, but even up close they look pretty dang good. mine is a titanium/black oem color. one of my main concerns was would the auctmart set match the oem tank scheme. i cant tell a difference.
i had to use an exacto blade to bore out a few holes where mounting bolts went through. where the headlight mounts to the upper the mounting tabs for a few of those bolts were just holes. same on the tail. i simply used the oem bolts to kind of "tap" threads into the plastic tabs. screwing them in and backing them out slowly. if you look closely in the pic of the tail, you can see the inner side of the fairings dont get the love oem do. you can see that mounting tab has a brass insert for screwing into. couple under the headlight didnt have the threaded brass insert. those were the ones requiring me to kind of tap with the bolts.
worked fine for me.
all in all i felt like the plastic itself was pretty close to oem in feel. it had plenty of flexibility. like nigel mentioned, maybe a smidgen thinner, only just though...
i feel like they were a good value for the money. took almost 1 month exactly from order date to arrive. tracking was more or less useless.
my tailpiece had a small scratch. i contacted auctmarts and they offered 50$ refund. which was fine with me. the scratch wasnt much and it more or less "buffed" out.
ive no experience with monster, but they come with a decent rep around the scene. im sure they are the same few actual manufacturers like nigel mentioned, just stored here in the us. so for the extra money they prob come to you faster, but i doubt they are much different in quality. just speculation though.
the first pics were just after fitting, potato camera. the others are this summer, 2+ years later.
