Side Door Bags for Polaris RZR 1000 XP 4 and Turbo S900: What to Look For

Quick answer

For Polaris RZR 1000 XP 4 and Turbo S900, prioritize door bags that mount to your specific door frame or roll bar, use reinforced straps or clamps, and keep contents out of the driver's leg zone. If you want a no-drill, high-capacity option that fits between the seats, the Kemimoto Center Console Bag for Polaris Slingshot S/R/SL/SLR/GT is a proven choice for reachable storage. For door-mounted storage, confirm the bag's listed fitment against your machine before buying.

Side door bags solve a simple problem: your RZR's cab has plenty of space to sit, but almost nowhere to put a phone, gloves, or a water bottle without it sliding under the seats. For four-seat machines like the Polaris RZR 1000 XP 4 and Turbo S900, door-mounted storage adds usable pockets right where passengers can reach them.

This guide gives you concrete decision rules for choosing UTV side door storage, including what to check before you buy, where door bags work best, and when a center bag or console bag is the smarter call.

Fit first: match the bag to your door and roll bar

The biggest mistake buyers make is assuming all RZR door bags fit all RZR models. Door frames, latch positions, and roll bar diameters vary between the XP 4 and Turbo S900. Before buying, measure your roll bar diameter and note whether your doors have flat panels or cutouts. A bag designed for a 1.75-inch to 2-inch round roll bar, like the Kemimoto UTV Rear View Side Mirrors for Can Am Maverick X3/ RZR w/ 1.75"-2" roll bar (1 pair), uses that same clamp range, so it is a useful reference point for what fits your machine.

If the product page does not list your exact model year, treat that as a decision limitation rather than a green light. Universal bags can work, but they often need extra straps or padding to stop rattling. Measure twice, then choose a bag with adjustable mounting hardware.

• Measure your roll bar diameter with calipers or a wrap of tape and a ruler.
• Check whether your door has a flat inner panel or a molded recess.
• Look for bags that list your specific machine, not just the RZR family.

Mounting method: straps, clamps, or bolt-on

Door bags attach in three main ways: straps around the door frame, clamps on the roll bar, or bolts through the door panel. Strap-mounted bags are the easiest to install and remove, but they can shift when you hit whoops. Clamp-mounted bags are more secure and often use the same hardware as side mirrors. Bolt-on bags are the most permanent and the most stable, but they require drilling, which many riders avoid on a newer machine.

For a four-seat RZR, rear passengers often kick the backs of the front seats, so a bag that hangs loosely will get knocked around. Choose a mounting method that keeps the bag tight against the door or seat. If you already run side mirrors with clamps, a clamp-mounted bag can share that real estate without new holes.

• Strap mounts: quick to install, best for light gear and occasional use.
• Clamp mounts: secure, no drilling, good for trail riding.
• Bolt-on mounts: most stable, but permanent and less flexible.

Capacity and layout: what actually fits

Door bags range from slim map pockets to multi-compartment organizers. Think about what you carry: a phone, keys, gloves, a small tool roll, or a water bottle. Bags with a concealed cup holder, like the Kemimoto Center Storage Bag for Can am Maverick X3 / MAX, show how useful a dedicated bottle slot can be. That bag adds about 2.8 gallons of capacity and includes small pockets for keys, wallet, and phone, plus a concealed cup holder.

For door-mounted bags, capacity is limited by door swing and legroom. A bag that is too deep will rub your knee or block the door latch. Measure the gap between your door and seat, then choose a bag that stays within that space. If you need more room than a door bag allows, consider a center console bag instead.

• Keep door bags shallow enough to clear your legs and the latch.
• Look for separate pockets so small items do not migrate.
• A cup holder is a small feature that makes a big difference on long rides.

Materials and weather resistance

UTV cabs see dust, mud, and rain, so bag material matters. Heavy-duty nylon or polyester with reinforced stitching holds up better than thin canvas. Zippers should be covered or water-resistant, and seams should be taped or sealed if you ride in wet conditions. Aluminum hardware resists corrosion better than steel, which is why many Kemimoto mirrors use aluminum bodies.

If you ride in extreme cold, stiff zippers and brittle plastic buckles can fail. Look for bags with glove-friendly pulls and metal buckles. Remember that no bag is fully waterproof unless it is explicitly rated; assume you may need a dry bag inside for electronics.

• Choose reinforced stitching and metal hardware where possible.
• Check for water-resistant zippers or flaps.
• In cold weather, test zippers before you rely on them.

Alternatives: center bags and console storage

Door bags are not the only option. Center console bags mount between the seats and keep items within reach of both driver and passenger. The Kemimoto Center Console Bag for Polaris Slingshot S/R/SL/SLR/GT installs between two seats near your shoulder and has a larger compartment in the back. It gives you extra room without taking up valuable space, and both occupants can access it easily.

If your priority is keeping gear out of the footwell and within arm's reach, a center bag may be more practical than door bags. For four-seat RZRs, a center bag serves the front row, while door bags can serve rear passengers. Many riders use both.

• Center bags: best for shared access and larger items.
• Door bags: best for passenger-specific storage and quick reach.
• Combine both if you carry gear for four people.

Decision rules for buying RZR side door bags

• Measure your roll bar and door frame: Use calipers or a tape wrap to confirm the diameter (common sizes are 1.75" and 2") and check whether your door has a flat panel or recess. If the bag does not list your exact model and diameter, keep looking.
• Choose a mounting method you can live with: Strap mounts for flexibility, clamp mounts for security without drilling, bolt-on for permanent stability. No drilling? Stick to strap or clamp mounts.
• Match capacity to your gear, not the biggest bag: A bag that blocks the door latch or rubs your knee is worse than a smaller one that fits cleanly. Measure the gap between door and seat before buying.
• Consider a center bag if door space is tight: Center console bags like the Kemimoto Center Console Bag for Polaris Slingshot S/R/SL/SLR/GT offer reachable storage without door fitment issues. For four-seat RZRs, a center bag plus door bags covers all passengers.

Product facts to know

• Center Console Bag for Polaris Slingshot S/R/SL/SLR/GT: Installs between two seats near your shoulder, has a larger compartment in the back, and gives extra room to put stuff within easy reach for both driver and passengers. A center bag keeps essentials accessible without using door space, and its position works well for shared storage in a four-seat cab.
• Center Storage Bag for Can am Maverick X3 / MAX: Increases storage capacity by about 2.8 gallons, includes many small bags for keys, wallet, and phones, and has a concealed cup holder. Shows the kind of capacity and organization to look for when comparing UTV side door storage options, especially if you need a dedicated drink holder.

Who this is for

Best for

• Polaris RZR 1000 XP 4 and Turbo S900 owners who want reachable storage for phones, gloves, and small tools
• Riders who prefer no-drill mounting and want to keep gear out of the footwell

Not for

• Owners who need fully waterproof storage for electronics in extreme wet conditions
• Riders who carry large coolers or bulky gear that requires a cargo box instead

Side door bags are a small upgrade that makes a four-seat RZR more livable. Focus on fit, mounting security, and realistic capacity, and you will avoid the rattles and rubs that make cheap bags regretful. If door space is tight, a center console bag is a smart complement.
