W-M807X Motorcycle Tire Changer (click here for detailed description)

  • Swing arm style mount/demount head
  • Automatic turntable mounting/demounting 
  • Four pneumatic clamps and double acting cylinders

  • Optional 30" Wheel Adapter Set

Which Weaver® Tire Changer is Right for you? (See chart below)

The only difference between the W-894XS and the W-898XS is the Clamping Range and Turntable Size.

*Note - Clamping ranges shown are not wheel sizes, they are clamp measurements.  Outside clamping is the typical method used to protect nice wheels.


By adding the optional W-C-M-0400000 MC/ATV Adapters to a W-898XS it will open to 30" when clamping from the outside of the wheel.  This means you could likely do most 28" wheels depending on the flange thickness and how that effects the overall diameter of the wheel. 

By adding the optional W-C-M-0400000 MC/ATV Adapters to a W-894XS it will open to 26" when clamping from the outside of the wheel.  This means you could likely do most 24" wheels depending on the flange thickness and how that effects the overall diameter of the wheel.


  • W-893 / 894 Series using inverted position: 7.5"-19"
  • W-893 / 894 Series using reverted position: 14"-26"
  • W-898 Series using inverted position: 10.25"- 23" 
  • W-898 Series using reverted position: 17"-30"

Note - The Bead Blaster will be out of position to assist seating the beads when using this adapter set.

W-PL230 Power Assist Arm (click here for detailed description)

  • Powerful pneumatic assist arm tire changer that attaches to the W-M807X Tire Changer
  • Powerful pneumatic lifting and pressing arm
  • Provides effortless mounting and demounting of tough low profile and run flat tires
  • Push or Pull beads into place with ease
  • Makes changing the toughest tires a one-man job

    I've never used a tire changer before, and there's a learning curve involved but this one does what it's supposed to. It seems to be well built and I'm sure it will serve my needs.

    W-M807X With Assist Arm

    Posted by Fred Burmer on 11th May 2021

    I'm extremely happy with the quality and functionality of this machine. My first project was to change the Front and Rear tires on my BMW K1600 GTL. This bike has a reputation for a difficult tire change due to the lack of a drop center on the wheels. This machine handled the job flawlessly. The shipping and packaging was fast. This is my 2nd product from Derek Weaver and I highly recommend doing business with them.

    DW 807 Tire Changer

    Posted by Mark on 26th Apr 2021

    Only used it once so far & very happy with this machine. Made quick & easy work of changing the 2 tires for our Honda shadow. Looked at this a couple of years ago & should have bought it then!!

    I have been working on bike for over 20 years and finally got sick of tire spoons and an aching back. Decided to purchase this machine and after I finished the first tire.. all I can say is I wish I had done it sooner. Great product and a very nice

    Great machine

    Posted by Tim P on 22nd Apr 2021

    Ordered the 807 w/ strong arm and found it easy to put together and was using it right away. I find this machine to be everything I was expecting. To sum up, a question I ask anyone is would I buy it again? No question the answer is yes. Great company and quick delivery.

    Worth Every Penny!

    Posted by JAMES YOGI on 12th Sep 2020

    I run a small powersports shop out of my home garage. I delayed a tire machine purchase for years - what a mistake that was. Looking back, I wasted hours of my time spooning tires when I could and should have purchased this machine from the start. This machine makes tire changes an absolute breeze. Although odd to say, this makes tire changing a pleasant experience. I opted for the power assist arm just to have that third hand available to me, and now, the process is almost effortless. A huge thanks to Derek Weaver for selling a quality product. I expect to have this machine for many years. Derek Weaver consistently answered the phone when I called during the buying process (I had a lot of questions). They were always professional, polite, and knowledgeable. Customer service is top notch and I will be purchasing another machine from them in the near future. If your budget and use justify the cost of a having a tire machine, stop overthinking it like I did and just buy it.

    Nice machine

    Posted by James on 11th Aug 2020

    Due to the covid BS it took longer to get this than expected, but it was worth the wait. The machine arrived well packed and undamaged. While these are very similar to Monarch, XK, etc, there are marked differences between these and the cheaper units. A friend bought an XK at the same time and he's kicking himself for not buying better. The Weaver machine is more stout and has better internals. My biggest complaint is the crappy lube container and mounting of same. I wish Weaver had a better option for this as mine falls off constantly and the lid won't even stay on the container. $1700 and I need to spend another $50+ to correct that. Minor, but a big annoyance. Buy this unit with confidence, but plan to use a different lube container. I'd also urge Weaver to produce a video for this unit specifically that focuses on its use including how to place the tire on the duck head/tail when mounting.

    Weaver® W-M807X Assist Arm Combo Motorcycle Tire Changer

    Posted by Mark Shively on 7th Aug 2020

    I'm an independent motorcycle technician and shop owner in the Ohio Valley. My decision to purchase the Weaver W-M807X with Assist Arm Combo was an easy choice. I compared the Weaver brand tire changers with other like and similar brands found on the internet. The only information I could get from other retailer's webpages and reviews were basic details and images about their tire changers. Weaver's webpage dedicates a page to their tire changer which includes manufacturing and design information. There's no guesswork comparing quality of Weaver's product. Weaver's tire changer videos featured music by my favorite band, RUSH. I've had my Weaver tire changer for about two weeks as of this writing. The delivery to my shop was hassle free. The wooden shipping container was protective and easy to disassemble. The tire changer was well packaged. Set-up instructions were easy to follow and perform. Set-up videos are on Weaver's webpage if needed. I'm very impressed with the quality of this machine. It will pay for itself very quickly. Buy Weaver products with confidence. Weaver's customer support is great.

    Best investment for my shop. Makes changing even the lowest profile tire a breeze. And not a single mark on expensive custom rims.

    Quality of the machine

    Posted by Brian on 12th Jun 2019

    After working with the owner of a reputable motorcycle repair shop last year in my area and using his machine (same model) and changing somewhere near 4 to 5 hundred tires, it was a no-brainer! Machine works flawlessly!

    Great Machine

    Posted by John Schlumberger on 8th May 2019

    This machine is great for changing motorcycle tires. I bought it for my small service shop where I change about 50 tires a year. So far I love it! This machine is well built from heavy gauge steel. Very good value at the price-point. It works just like the "professional" machines that are triple the price. Once you figure out the little tricks, changing tires with this machine becomes a breeze. I would highly recommend this machine to any small shop or DIY motorcycle guy. I have not tried to change a car tire with this setup, but it appears it would be easy enough.

    Cannot compare since this is the first tire changer I have ever used. However, it was delivered promptly, in excellent condition and seems to perform as advertised. I believe I will get many years of service from this machin

    Great machine, Great price

    Posted by Al on 3rd Nov 2016

    I believe the assist arm attachment is a must for low profile wide street tires. Great extra hand.. Machine is easy to use and set up. A must at a good price if your changing more then one tire a year. I could never use my manual machine on the newer rims and tires. They would get wasted in the process.

    I needed a good tire changer to change tires on my bmw k1600gtl. The rear tire is so stiff I could not do it manually. My new weaver handles the job with ease so now changing tires is no problem

Derek Weaver Company is proud to offer our high quality products with free shipping or warehouse pickup. Here's how it works...


All Products on our website are offered with "Free Shipping". This means the freight charges are included in the price. Most of our products weighing less than 800-lbs. are offered with “Absolute Free Shipping” which means there are no extra fees. In this case you will notice the phrase “FREE SHIPPING! Includes Free Residential and Free Lift Gate Service!”, in the description of the products page. Absolute Free Shipping also means there are no additional fees for Liftgate Service or Residential Delivery. The only additional fee that you may incur would be if the address were changed during shipment which would incur a reconsignment fee by the freight carrier that we would only pass on if it were not our mistake.

For equipment over 800-lbs (most 2 & 4-Post lifts) there are some limitations for Free Shipping depending on weight and delivery location. In this case you will notice the phrase “Free Shipping To Over 85% of the USA - See Where It's Free” in the description of the products page. Most of the USA will require no additional fee. This applies to over 85% of the continental USA (lower 48 states). Free shipping does not apply to Alaska or Hawaii. Some parts of the country are affected by higher freight rates due to the combination of weight and delivery location which will require a small additional charge to cover the higher rate charged by the freight carriers. Our shopping cart will not calculate the difference (added fee), so we will contact you if this is the case. Rather than advertise the higher rates across the board we choose to show the lowest possible cost to most of the country. Like “Absolute Free Shipping” there will be no extra charge for lift gate or residential delivery. The following areas may have additional freight: North Western US, North Eastern US, Long Island, Western Colorado, the Dakotas, some parts of Florida & California and any area deemed a remote location by the freight company. Prior to ordering give us a call at 817-560-9510 or email and we can provide accurate information regarding Free Shipping or any additional charges.


Shipping and delivery time given during the freight quote process is an estimated time of delivery given by the carrier. Choosing Liftgate Delivery may extend delivery times due to limited liftgate equipment at the delivering terminal. Meeting the delivery schedule is subject to the day the freight is shipped and the carrier’s ability to meet their schedule. Derek Weaver Co., Inc. does not guarantee that a carrier can meet their projected delivery time but we will provide you with the proper tracking information by email so you can follow the tracking time and arrange for special delivery needs with the carrier as needed. Any additional fees incurred as a result of consignee being unable to meet scheduled delivery time or cause for redelivery or reconsignment to a different location will be at consignee’s expense.


Choosing Residential may extend the estimated delivery time due limited liftgate trucks at the delivering terminal, additional communication and handling by the freight company. Please keep this in mind when choosing residential delivery.


Make sure you can unload the freight. A forklift or lifting equipment is required for items over 800-lbs. The trucking company is only responsible for delivery to your loading dock if delivered to a business address or curbside if a residential lift gate delivery. Lift gate service is available for some equipment and can assist in unloading 2 and 4-post lifts however you will still need a forklift. Liftgate capacity is typically 1000-lbs and cannot unload a 2 or 4-post lift on its own.


If you are unable to unload a truck, we have the option of letting you pick the freight up at the closest terminal to your location. When picking up at a terminal, the freight company will load your truck or trailer for you which is included in the freight cost. Call our office (1-817-560-9510) to determine the location of the closest terminal. If you require terminal pickup please place a note in the comment box requesting terminal pickup and we will contact you with the terminal location. Covered trailers or trailers with ramps are not acceptable as they prevent the forklift from getting the load into the trailer. They will not drive onto a ramped trailer. Please remove the ramps prior to picking up if possible.

All shipments must be inspected immediately upon receipt



Choose this option if you have minor dings and scratches or a part that needs replaced to make the unit satisfactory. Make note of the damage before you sign the freight bill. You will be responsible for filing the freight damage claim with the carrier. Derek Weaver Co, Inc. will provide any replacement parts or touch up paint needed should you choose this option and the carrier should provide for reimbursement. If you have any questions or need further assistance, please call our customer service department @ 1-817-560-9510


Choose this option if the carrier has severely damaged the freight beyond your judgment of a simple repair. Derek Weaver Co, Inc. will file all freight claims. Get a copy of the freight bill from the truck driver and email it with a brief explanation of the situation to us. A replacement will be shipped as soon as we verify possession of the freight with the carrier.


If you would like to pick-up the item at one or our warehouses, please call ahead to make sure the item is in stock and schedule your pick-up. Picking up at our warehouse will save you in freight fees but will require sales tax to be collected. If you do not see a pickup price on our website for the product you are interested in you may call our office for more information.

All Two Post and Four Post Lifts require trailer for pickup. Be prepared for pick-up by understanding the item’s weight and dimensions and using the proper truck and/or trailer for hauling. We cannot load open or enclosed trailers with ramp gates. Our warehouse will load the item onto your vehicle and/or trailer but is not responsible for properly securing the load on your vehicle and you will need to make sure you have the proper straps and equipment for hauling.
