Our Yamaha WR250R Dual Sport project bike has the following mods and accessories...

I'd left my WR250R's engine stock for the first couple summers I owned the bike, then decided it was time to do some performance-oriented mods. The first thing I did was replace the stock muffler/mid pipe/header with our FMF Q4 Performance Exhaust Package, which consists of an FMF Q4 muffler, FMF Megabomb header, and the optional EJK Fuel Injection Controller, 12oClockLabs EXUP Emulator and AIS Removal Kit. At the same time, I replaced the stock air filter with a No Toil Super Flo Filter Kit. I couldn't be happier with this setup.... the FMF Q4 System is my favorite exhaust for these bikes... it sounds great without being obnoxiously loud, it's quite a bit lighter than the stock exhaust, and it adds a significant amount of performance. Gone is that dead spot early in the powerband, the bike is now much more fun to ride, and it actually sounds like a motorcycle now instead of a lawn mower! Here are the links to the Engine mods we did...
  • FMF Q4 Performance Package (Q4 muffler, Megabomb header, EFI Controller, EXUP Emulator, AIS Removal Kit)
  • No Toil Super Flo Filter Kit

    Like most dual sport bikes, the stock tail light and front/rear turn signals on the WR250R are very large and definitely takes away from the looks of the bike. I wanted something that would clean up the rear fender area and also wanted to get rid of the large front turn signals. Since I wanted to add hand guards anyways, I went with our Zeta PRO Armor Hand Guard Package with integrated turn signals. This really cleans up the front of the bike and adds some well-needed protection as well. Out back I ditched the huge stock tail light and turn signals, replacing them with our nice and compact DRC Edge2 Integrated Tail Light Kit. These simple changes make the bike look so much better!! Here are the links to the Lighting mods I did...
  • DRC Edge2 Integrated Tail Light Kit (red lense)
  • Zeta PRO Armor Hand Guards with XC Flasher Protectors
  • 12oClockLabs Edge2 Processor Upgrade Board
  • 12oClockLabs Turn Signal Running Light Adapters
  • 12oClockLabs Fixed Rate Turn Signal Flasher
  • Cyclops Rally Headlight
  • Cyclops 3800 Lumen H4 LED Headlight Bulb (fits stock headlight too)
  • 12oClockLabs SpeedoDRD Speedometer Calibrator
  • 12oClockLabs Gear Position Indicator

    If you're doing any type of off-road riding on your WR250R, there are several things you'll need to consider to help protect her from damage. The first thing I did was remove the worthless OEM plastic engine protection, replacing it with a Flatland Racing Skid Plate. Next I pulled off the plastic radiator protection, and replaced it with a Flatland Racing Radiator Guard. Both of those items provide needed protection to vulnerable parts of the engine. The stock drive cover was swapped for Sandman Parts Freedom Case Saver. The bike also desperately needed hand guards, so I went with the new Zeta PRO Armor Hand Guard Package with XC PRO Protectors and Integrated LED Turn Signals. This not only cleans up the front end of the bike, but it provides some excellent protection. Here are the links to these mods...
  • Flatland Racing Skid Plate
  • Flatland Racing Radiator Guard
  • Zeta PRO Armor Hand Guards w/ XC PRO Protectors and Integrated LED's
  • Zeta Heel Guard/Chain Cover
  • Z-Carbon Frame Guards
  • Zeta Front Brake Disc Guard
  • Wolfman Kiowa Muffler Heat Shield
  • Sandman Freedom Case Saver Kit

    We've upgraded the stock handlebars to a set over oversized 1 1/8" Pro Tapers, and also added Zeta PRO Armor handguards with the integrated LED turn signals. While we were at it, we also did one of the G2 Tamer Throttle Tubes to help with the WRR's snatchy on/off throttle, and replaced the grips and levers as well. The stock mirrors were quickly replaced by a set of super durable Doubletake Enduro mirrors. Here are the links to these mods...
  • Pro Taper Contour Handlebars, 1 1/8", Woods High Bend
  • Zeta RX2 Handlebar Clamp Kit
  • Zeta PRO Armor Hand Guards w/ XC PRO Protectors and Integrated LED's
  • G2 Tamer Aluminum Throttle Tube
  • Double Take Dual Sport Mirrors
  • Short Clutch and Brake Lever Set
  • Pro Taper Pillow Top Grips
  • 12oClockLabs Gear Position Indicator

    The stock seat on the WR250R is not well-suited for the long rides I was doing on the bike. After trying out few different seats, I settled on one from Seat Concepts and couldn't be happier. The seat is substantially wider than the stock seat and uses a much more comfortable foam material. I went with the Low Foam version so it also helped with the tall seat height. Now those 250 mile rides are a breeze! The stock footpegs were also one of the first things I replaced... they are way too narrow and don't provide much grip. Currently I'm using Pro Moto Billet Evo Air footpegs, which are the ultimate footpegs for these bikes... and they even come in blue! I've also added a very trick DRC folding rear brake pedal in Black/Blue. For a cargo rack, there was no question which way to go...the popular Pro Moto Billet Rack, which is not only beautifully CNC machined, but functional as well. Here are the links to these mods...
  • Seat Concepts Complete Seat (Low Foam Height, Blue/Black Gripper Cover)
  • Zeta Aluminum Footpegs, Blue
  • Zeta Trigger Folding Rear Brake Pedal, Blue
  • Pro Moto Billet Rear Cargo Rack
  • Zeta Folding Shift Lever

    These bikes are tall, and at 5'9" with a 30 inch inseam, I could never get comfortable with the stock seat height. A Yamalinks Lowering Link helped lower the seat height about two inches when combined with the factory lowering option, and a Seat Concepts Seat with their Low Seat foam lowered the seat height another 3/4"...
  • Yamalink Lowering Link (Blue)
  • Seat Concepts Complete Seat (Low Foam Height, Blue/Black Gripper Cover)

    The stock 2 gallon gas tank on these bikes is inadequate if you're doing long rides... unless you like stopping for fuel every 100 miles or so. I decided that an extra gallon of fuel would be ideal, so I installed the IMS 3.1 Gallon Gas Tank and now I get upwards of 150-200 miles of range, depending on how I twist the throttle. Here are the links to these mods...
  • Yamaha OEM Plastics Kit (Black)
  • IMS 3.1 Gallon Gas Tank (Black)
  • Retro Yamaha Tank Graphics
  • 12oClockLabs SpeedoDRD Speedometer Calibrator
  • Zeta Oil Filter Cover
  • Zeta Blue Billet Kit
  • Zeta Magnetic Drain Bolt, Blue
  • DRC Radiator Hose Kit, Red

    Off-Road Wheels/Tires:
    The OEM Bridgestones that come on these bikes are horrible if you are doing any serious off-road riding. I pulled mine right away, and replaced them with the popular Dunlop D606 Rear Tire and Pirelli MT-21 Front Tire...
  • SM Pro Platinum Dirt Wheels
  • Dunlop D606 Rear Tire (120/90-18)
  • Pirelli MT-21 Front Tire (90/90-21)
  • Michelin Inner Tubes
  • Motion Pro Rim Locks

    Off-Road Drivetrain:
  • DID 520 ERVT Chain (Gold)
  • DRC Dura Rear Sprocket, Black, 46T (stock size is 43T)
  • Sunstar Front Sprocket, 13T (stock size)

    Supermoto Wheels/Tires:
    I do quite a bit of street riding with my WR250R, so a set of Supermoto Wheels and Tires was a must. A good street tire like the Bridgestone S20 Evo Hypersport Tires will provide so much more grip than any knobby tire ever will...
  • Warp 9 Elite Supermoto Wheels
  • Bridgestone S20 Evo Hypersport Front Tire (110/70-17)
  • Bridgestone S20 Evo Hypersport Rear Tire (140/70-17)

    Street Drivetrain:
  • EK 520 MVXZ X-Ring Dual Sport Chain, Gold
  • DRC Dura Rear Sprocket, Black, 42T (stock size is 43T)
  • Sunstar Front Sprocket, 13T (stock size)

  • Pro Moto Billet Cargo Rack
  • Nelson Rigg Trails End Dual Sport Enduro Tail Bag
  • Firstgear Torrent Waterproof Duffel Bag

  • DRC Lift Stand
  • Longacre Digital Tire Gauge
  • Battery Tender Jr.
  • Cruz Tools Outback'R M14 Tool Set

    That's it for now, but stay tuned. We have more plans for this bike... here's some of what we'll be adding...
  • Scott's Steering Stabilizer
  • ... and I'm sure there will be more...
