Communication was on point and the fella worked with me on my address.
The good stuff
Awesome
Excellent fit and finish. Easy installation with no modification required
Supreme oversuspenion for my BMW M1000XR COMPETITION
One of the best purchasing experiences I've had. Customer service and communication is excellent.
They're a little tricky to install if you leave the radiator on the bike, but doable with minimal tools. The fit and finish can't be beat.
professional and very nice conversation and customer service even i did some mistake and they fix it
thank you 🙏
Very happy with the shock. HHR was great!
Easy fast and what I wanted
Love it, wish it came in twill weave gloss but it is on sale and fit and looks amazing! Just ordered frame carbon fiber from here as well to match !
I ordered this part for my r6.
Got a email back about 4 days later saying I didnt order the correct lines for it.
HHR didnt have to do that. I would not have known they took the time to make sure i got the part the first time.
I appreciate that alot. Integrity in this day and age seems to be long forgotten thing.
Will be ordering more parts as I need them and will use HHR for them.
Awesome piece and fits perfect. Definitely recommend getting this over the standard version, which I also have. This one pan is 30mm lower. Also make sure you get the Alpha seat Support bracket if running the stock subframe in addition to the mounting kit.
8mm swingarm spools such a great design very strong and doesn’t weigh nothing there not so big so it doesn’t stand out it’s perfect
Great experience
