The Mugen MBX8 1/8 Off-Road Competition Buggy Kit offers improved durability, more acceleration and increased runtime, in an easier to work on, lightweight platform.

NOTE: Engine, tuned pipe, electronics, wheels and tires shown in photos are for illustrative purposes only and are not included. See needed to complete list below for a full list of items required to complete the model.

MBX8 Features:

  • Chassis: The MBX8 chassis features an updated material that is more rigid and durable. The chassis improves steering and is more consistent in bumpy conditions.
  • Differential and drivetrain: High Traction Differentials are included in the MBX8. The Mugen Seiki HTD provides increased acceleration, longer runtime, and more consistent handling. The HTD’s also increase stability, traction and improve handling in bumpy conditions. The HTD has a larger volume diff cup to increase consistency during long main events. This makes it easier to time rhythm sections, better in bumpy and low grip conditions, helps to increase traction, and increases fuel mileage. 
  • Updated straight cut 13T bevel gear & 44T conical gear: The straight cut bevel and conical gears increase acceleration, runtime, and efficiency. A free and efficient drivetrain will also increase speeds while cornering. 
  • Lightweight one-piece wing mount: The updated lightweight one-piece wing mount lower the center of gravity. The position of the wing and wing mount is optimized to improve the performance of vehicle. The height of the wing mount is adjustable. This allows you to control the down force on the rear of the vehicle by simply raising or lowering the mount on the shock tower. 
  • Lightweight high down-force wing: The updated IFMAR legal wing is lightweight and provides amazing down force and corning. The underside of the wing uses an updated design to reduced weight and creates additional down-force.
  • Suspension: The Front Front/Front Rear and Rear Front/Rear Rear suspension blocks have been redesigned for the MBX8.
  • Front and rear gearbox: Easier access to the front and rear differential. The updated gearbox allows you to remove and service the differentials without detaching the suspension arm mounts.  
  • Box-shaped suspension arms and arm stiffeners: The front and rear lower arms use an updated impact resistant material for increased durability. The redesigned arms are box-shaped and include arm stiffeners to reduce flex and increase durability. Adjusting the hardness of the lower suspension arms is now possible. This allows you to fine tune the steering and traction from track to track. CFRP plates will be available as an option part (not included).
  • Center differential mount & plate: The center differential mounts use a stiffer material and a redesigned top plate to reduce chassis flex and increases clutch bell, spur gear, and clutch bearing life. The reduced chassis flex also provides more consistent handling in all conditions. The top plate design also makes it easier to adjust the brakes and easier maintenance.
  • Enclosed Battery box and updated carbon fiber radio plate: The MBX8 still uses a flat 2S LiPo or LiFe receiver battery, but the battery is now enclosed in a molded battery box. The battery box allows for quick and easy access to the battery. The molded box also helps protect the battery from hard impacts. The battery box is mounted to an updated carbon fiber radio plate.
  • Other Updated parts and upgrades: Body, Clamping Servo Saver Nut, Front/Rear Shock Towers, Front bumper, Front center and rear center universal joint.

  • Big Block Nitro Engine

Mugen Seiki MBX8 1/8 Off-Road Competition Nitro Buggy Kit
Guten Tag, ich bestellte dieses Set des Mugen-Konzerns, die Montage war verantwortungsbewusst und normal, an einigen Stellen habe ich ein Messer zum Entfernen des Differential-Kunststoffs verwendet, der Kauf erfolgte am 05.04.2013. Das Modell hat 4 Rennen der Grand Tour bestanden, ich bin 4 Stunden hintereinander von einem Kollegen mit einem Modell gefahren und habe den Crash des Modells im Moment der Verantwortung verlassen. MUGE2144 + MUGE2146 sind nicht zum Rennen gekommen, danach musste das Modell verkauft werden.

Mugen Seiki MBX8 1/8 Off-Road Competition Nitro Buggy Kit
1 model keeps going straight on; at the exit of the turn, the problem is always to go straight.
2 eternal sores of these models starting from the 6th series of models, the differential gear case breaks down, we buy spare parts every stage.
3 marketing company pulling your money out of your pockets!
4 prices for parts are huge, especially for bearings.
5 raised the price by $ 150 and for what? a little bit did everything like that of HB racing.
Extremely dissatisfied with the model!

Mugen Seiki MBX8 1/8 Off-Road Competition Nitro Buggy Kit
Really did my research when it came to a nitro kit, I have been wanting one for a long time. I ended up choosing the MBX8 and so glad I did the build was super easy and the parts they use are top notch. Mugen support is awesome too if u need any parts they are located in Cali, or Amain has pretty much every part aswell. So 5 stars for quality and 5 stars for ease of putting together.

One of the top cars on the market. There isn’t any differences or price point when comes buying this kit it’s equal piece when comes to up keep you stay up on the routine maintenance and you don’t have to replace very many parts only one due to wear out. I have have all 4 8 series cars I had all the 7 series vehicles too. Amain it a great place to do business with also! I love my 8 been running mugen for 4 yrs now.
