Terrible customer service

I ordered from Sierra BMW on 4/29/2026. I emailed, called, and even sent text messages more times than I can count just to get a status update. At least a month went by with no response. No shipping confirmation. No info the order was delayed or on back order—-nothing. When the company finally responded, it was to say my item was on back order. On 7/13/2026, my item was finally delivered. Ridiculous company. Will never do business with them again.

Good design, quality, but poor execution on details at this price

As with every AltRider item I've ever purchased for a BMW they seem to ignore the details of the motorcycle in their accessories hardware. There's just no reason for this price to not include stainless torx hardware that corresponds to everything OEM on the bike. Just frustrating to have to EASILY source the same hardware in torx for consistency AFTER purchase when this should just be the way AltRider does things.

Took them over 2 months to deliver!

Crash bars and risers

I had Good coorespondence with Sierra BMW. Everything arrived brand new with all hardware. They were easy to assemble. Looks great and will function well, Thanks you all!

C5 carbon fiber

This helmet is worth every penny. It makes the freeway tolerable and good air flow. I just used ot for a 7 day motorcycle trip from michigan to west virginia to ride in the mountains and back. We got rained on a few times and had some freeway driving. This helmet is a game changer. For the communication gear I did the edge. Super easy to hook up, my husband and I can speak via intercom even though he has the older model communication gear. Good battery life. Highly recommend.
