The Sargent Cycle World Sports Performance Plus standard height seat with CarbonFX upholstery and black welt is a worthwhile upgrade for the 2025 BMW F 900 XR. (Photos by the author) When I got my 2025 BMW F 900 XR, it didn’t take long to discover that the stock seat just isn’t comfortable. Even on shorter rides, my backside soon ached. The seat’s shape locked me in place so I couldn’t easily adjust my body position. And BMW does not offer factory heated seats for F-series bikes.   On two previous BMWs, I had World Sport Performance Plus seats from Sargent Cycle Products. I found them superior to stock seats, so I got another. The seating surface is a bit wider than stock and contoured to enhance lateral support and distribute pressure evenly. I can adjust my body position for spirited riding, navigating tight spaces, or simply changing positions on a long ride. The central “relief” channel, where a strategic bit of seat foam is removed, takes pressure off the crotch and tail bone.   Super Cell Atomic Foam is Sargent’s secret sauce combining resilience, firmness, and vibration-absorption. Below the foam surface is an embedded layer of memory foam that absorbs pressure points. Under it all is Sargent’s PolyTech seat pan, injection-molded from a tough, lightweight polymer. The pan has a special recess for the included rechargeable LED flashlight.   There’s optional seat heating, either single zone for just the rider or separately controlled dual zones for rider and passenger. Each zone draws approximately 1.7 amps (23 watts at 13.5 volts). Sargent’s waterproof HeatBoss controller has a rotating knob and blinking red LED, so it’s easy to dial in the desired heat level. I think the simple-is-good approach of the HeatBoss is a noteworthy upgrade over Sargent’s earlier membrane switch controller. Attach the HeatBoss to a body panel using supplied hook-and-loop, or choose one of Sargent’s optional mounts for the handlebar clamp or mirror post. I prefer the handlebar mount since its vertical orientation prevents the HeatBoss from contacting my tank bag, even at full lock.  Sargent’s waterproof HeatBoss controller is easy to use, with a simple rotary dial and an LED that flashes according to heat level.

Compared to the previous flat wire, the new wire is easier to route for a neat installation. There’s a new quick disconnect too, so if you ever need to remove the HeatBoss, you won’t have to remove the entire harness.   Sargent seats are made in the USA and sewn by hand. Options for the marine-grade upholstery include CarbonFX or DTX, with or without “grip zones,” which are special panels on the front sides that help your inner legs grip the seat (useful for standing on adventure bikes). There are multiple color options for stitching and welt. To complement my XR’s Triple Black colorway, I chose black CarbonFX upholstery and black welt. I think it looks fantastic and is a noticeable upgrade over stock.  With several hundred miles, um, behind me, Sargent’s World Sport Performance Plus seat is proving both plush and supportive. The butt pocket is wider and more gently contoured than the stock seat, so I can easily adjust my body position. And it’s easy to dial in heat to add comfort that BMW doesn’t offer.   See all of Rider‘s Parts & Accessories Reviews here Sargent Cycle makes World Sport Performance Plus seats for dozens of motorcycle models, plus REVolution seats using your bike’s OEM seat pan and a range of custom seat services.
