BOYIMU phone mount: stem-mounted, with a USB charger
The BOYIMU Motorcycle Phone Mount with Charger plugs into the open center hole of your bike’s top triple clamp, holds the phone in a four-arm cradle and charges it from the bike’s battery. It’s made for sport bikes: Hayabusa, GSX-R, Ninja, R6, CBR and the S1000RR.

Features of the BOYIMU Motorcycle Phone Mount with Charger
Start with where it goes. This isn’t a handlebar clamp. It slides into the center hole of the top triple clamp, the steering stem yoke, and the listing text gives that hole as 16 to 19 mm, while its photos show two stem inserts, one for 13 to 16 mm and one for 16 to 19 mm. The fitment list reads like a sport-bike lineup: Suzuki Hayabusa and GSX-R 600, 750 and 1000, Yamaha YZF-R1 and R6, Kawasaki Ninja 250, 400, ZX-6RR and ZX-14R, Honda CBR 250R through 600RR and the CBR600 F4i, plus the BMW S1000RR. The listing’s images add year ranges and more models than its bullet points, and a parts retailer’s page carries year ranges too, so check yours before ordering.
On top sits a 1-inch ball joint with a locking collar. The cradle turns 360 degrees, for portrait or landscape. The grip is an X-shaped clamp with four arms, a rubber band that hooks over the phone’s four corners, and soft rubber pads where the arms touch the phone.
The charger is the headline. A USB port is built into the mount, and you wire it to the bike. One buyer on a ’97 Suzuki RF900 says the cable reached the battery with room to spare and the unit has an on/off switch, so it doesn’t drain the battery when parked.
The rest comes from the listings. Amazon gives about 12.6 ounces, black, and rubber as the material; a parts retailer that carries the same model adds ABS plastic and metal. Phones from 1.75 to 4.5 inches wide and 3.25 to 5.5 inches tall, says the listing text; one of its photos says up to 3.9 inches wide. The listing also names recent iPhones, which runs into its own height limit; buyers fill that gap below. And Amazon lists it as not water resistant.
BOYIMU, a motorcycle-parts brand on Amazon. Ships from Amazon with 30-day returns
BOYIMU sells motorcycle parts on Amazon: side cases, wheel rim decals, fender eliminators with LED lights, a blind-spot mirror, and this phone mount, the only one in its catalog there. The listing shows it ships from Amazon, is sold by a third-party seller, and comes with Amazon’s 30-day refund or replacement.
Why does the BOYIMU Motorcycle Phone Mount with Charger cost what it does?
It’s a budget mount, and buyers treat it that way. One rider with several bikes puts it at about a third of what name-brand versions cost. You can see where the money went. In one box you get the charger, the stem mount, two stem plug sizes and an offset bracket. What you don’t get is a ball joint that holds still: several buyers say it keeps moving even when tightened. The grip leans on rubber parts, and the USB module is where most complaints land. The current price is on Amazon.

Buyers keep holding it up against RAM. A Gen 1 Hayabusa owner looked at RAM first, found the option he was considering had no charging port, and went with this one. A rider in Canada says it beats the RAM equivalent and stays steady at speed. On the other side, a GSX-R750 owner gave up on it after the clamp loosened and the ball broke in half, and moved to a name-brand mount. Another buyer calls Quad Lock the best system.
The trade-off is plain. The BOYIMU puts charging and a stem mount in one cheap unit. The GSX-R750 rider above ended up with a pricier name-brand mount after the ball broke.

Benefits of this BOYIMU phone mount
The stem hole puts the phone dead center, above the clamp, where the instruments are. A 2005 Hayabusa owner says it sat tight in the yoke with no movement unless he moved it, and a ’97 RF900 owner says it fit his stem perfectly. The job is short. One rider says the install and the wiring took about 15 minutes, part of it spent pulling fairings. Others call it easy too, though one found the hardware fiddly and needed patience.
Other benefits of the BOYIMU phone holder
Charging while you ride is the headline feature. An XR650 rider says it charges his phone fine. The RF900 rider says it charged for two straight weeks, quickly, with no battery drain. Grip holds up under abuse too. One buyer went down at 30 to 40 mph after a truck brake-checked him, and the phone came through. Another low-sided at 65 mph and the phone stayed put, though he had removed the rubber band, which he doesn’t trust, and bent the arm ends inward. Wheelies and trail riding on the XR650 didn’t shake it loose.
What riders say about the BOYIMU motorcycle phone mount
Video first. The only YouTube clip I found that links this exact mount is a GSX-R 750 owner’s walk-through of his mods. He bought it on Amazon and lists it among his upgrades, without saying how it performs. The retailer pages that carry it repeat the manufacturer’s description and have no buyer reviews. So the real feedback is on Amazon.
The happy buyers talk about an easy install, a snug fit in the stem and a phone that stays put. A Gen 1 Hayabusa owner picked it over RAM for the charging port and says there’s no movement unless he wants it. An RF900 rider took it to the track and says it held the phone and charged it for two straight weeks with no battery drain. An XR650 rider says wheelies and trail riding didn’t shake it loose, and a rider in Canada says it stays steady at high speed and that the charger has a short cable. One GSX-R 600 rider put 16,000 miles on his first one over three to four years and bought a second; a charging port working loose in its housing is what retired it. Two buyers call it good value for the money, and one says the seller reached out on his own to sort out a fitment issue.
The complaints cluster in two places. Several recent reviews say the USB port stopped charging after a day, a few days or a month, while the mount kept holding the phone. And the stem plug can work loose: one rider re-tightens it two to four times a week, and a GSX-R750 rider had the clamp loosen mid-ride before the ball broke in half overnight. Smaller gripes: the rubber band blocks buttons, pads come off, one buyer says the rubberized surface melted, a 2017 CBR1000RR owner says the plug didn’t expand enough to grip the stem, and one buyer couldn’t get through to support. On phone size, one rider says an iPhone 14 Pro is about the largest that fits, while another fits a Note20 Ultra with room to spare.

Conclusions on this BOYIMU phone mount
If your bike has an open stem hole and you want charging in one cheap unit, the BOYIMU covers that. A Gen 1 Hayabusa owner and an RF900 rider report a snug fit and a phone that stays put; a GSX-R750 owner and a CBR1000RR owner had the opposite experience. The weak spots are the USB module and the ball joint, and Amazon lists it as not water resistant. If you ride daily in the rain or carry a large phone, a sturdier system may suit you better. The call is yours.
