Just curious on what some good aftermarket parts other people have and like?

I love my hiper rims
Houser steering stem
Houser swing arm
HMF Bill Balance full exhaust
These are only me favorite out of many

Let us hear what you have

im happy with all the products i have, some have poor customer service, but the product is top notch...

gibson, fox, tag, blingstar, quad tech, maier, gytr, any of these make a stand up product in my opinion

Pro Armor for sure they have good stuff i think

houser is awesome! my lonestar swing arm on the yami sucks! the bearing carrier part on the swing arm cracked away from the two arms and also it cracked in a couple other spots. but other then that pro armor streamline and protaper bars. also cycria bark busters are tuff as hell.

I have to give props to my tusk handguards. Better than my powermadds by far and a heck of a lot cheaper. I also have tusk chub bars and nerfs, cant beat the quality for the price A+ in my book. I didn't have as good as luck with houser swinger, but they have redesigned the swinger since I got one probably to take care of the issues from earlier makes. I did like their steering stem though. +1 on hipers but also have had good luck with douglas as well. And the two pro armor bumpers I have bought have been great quality and looked good as well. If the rest of their products are like this I would buy them as well.
One company I would like to buy from is rath. I have heard nothing but great things about them, but maybe when I am richer

IMS/Roll Design GP Series Pro Peg Nerf Bars:
The installation was pretty bad. The crossbar fell right inline with the quads chassis support. Because of this I had to mount the crossbar BEHIND the chassis support rather than in front of it like it is supposed to be. However, I over jumped a 4th gear hit and flatlanded and the nerfs stayed on rock solid. The bolts did not even loosen. I would not suggest these nerfs for the casual rider who wants to use his/her stock heel guards though because they will not mount up. You must purchase the matching GP Series Heel Guards. However, I have no complaints other than the installation. The Pro Pegs are awesome and provide excellent grip. These nerfs are super strong and have held up to getting hit in races and flatlanding jumps. All in all, GREAT product.

Blingstar nerfs ar good, FMF factory 4.1 pipe, esr airbox eliminator, parking brake block off, gytr heelguards, dyno jet jet kit, protaper pillow top grips are amazing, billet gas cap

+ 1 on the pillow tops....I LOVE THEM. the only grip I'll ever run

Quadtech, ITP, Maxxis, Oury grips, Regina Chains, IMS-Roll, Pro Design, FMF, Jardine, Cascade, DFR, Tag are all pretty good. My AC propegs I really like but they're not very heavy duty.

MMAD pipe, RIS pipe, fireball arms, JJ&A, also +1 titanium valves and lightspeed cams
