KTM Adventure models are among the most versatile motorcycles on the market. From touring to off-road and rally use, they can do almost anything. But one area is becoming increasingly popular: conversion to true Supermoto performance.
A precisely tuned Supermoto wheelset transforms any KTM Adventure – whether 790, 890, 950, 990, 1090, 1190, 1290 or 1390 – into a precise, agile road and track tool.
In this article, you’ll learn which components truly make sense, what you need to look out for, and why so many riders specifically choose FaBa Strong or Excel Takasago rims.
Why a Supermoto conversion makes sense for the KTM Adventure
The large Adventure models from Mattighofen have a lot of power, stable geometry, and a strong braking system. These very characteristics make them surprisingly well-suited for a Supermoto conversion.
The advantages:
– significantly more precise steering
– more agility and higher stability at high speed
– better tire choice for road and track
– shorter braking distance thanks to low center of gravity
– more direct feel in fast corners
With a properly tuned 17-inch wheelset, the Adventure feels like a new motorcycle.
Optimal Wheel Sizes: 3.5x17 and 5.5x17
Two sizes have proven themselves for the Supermoto conversion:
Front: 3.5x17
– ideal for sporty road tires
– precise steering
– compatible with all modern Supermoto tire profiles in size 120/70 R17
Rear: 5.5x17
– optimal tire width in size 180/55 R17
– perfect traction
– clean line holding even at high power
These dimensions provide the typical Supermoto handling and work surprisingly well on the heavy Adventure models.
Which rims are suitable? FaBa Strong vs. Excel Takasago
FaBa Strong Rim Rings
– made of high-quality 7075 aluminum
– glass bead blasted
– anodized in a silky matte finish
– extremely stable
– ideal for heavy Adventure bikes
FaBa is known for very robust rim rings, especially popular with rally and off-road riders.
Excel Takasago Rims
– 7075-T6 aluminum
– polished and brightly anodized
– high concentricity
– light and very precise
Excel is the premium solution for sporty use and track days.
Both systems work excellently on the KTM Adventure – the choice is more a matter of taste or intended use.
The Hub: Cushioned and CNC-milled
For the Supermoto conversion of Adventure models, we recommend a CNC-milled, cushioned hub from Nuova Faor.
It offers:
– high load capacity
– perfect fit
– clean workmanship
– stable damping of the drivetrain
Especially with powerful engines like the 1290 and the new 1390, a good cush drive is mandatory.
Spokes & Nipples: Alpina Quality
FaBa and other manufacturers rely on Alpina carbon steel spokes – chromed, high-gloss, extremely durable.
Alpina nipples made of aluminum or steel are also used.
This combination has proven its worth on heavy travel enduros and adventure bikes for years.
Tubeless or Tube? The Options
For Supermoto use, we recommend a tubeless system because it:
– reduces weight
– improves riding stability
– makes handling noticeably more precise
With the optional BarTubeless System, you get real tubeless rims without an inner tube.
ABS and Traction Control – does it work?
Yes, with our special Supermoto ABS ring, both continue to function reliably.
For every KTM Adventure Supermoto configuration, we supply:
– the appropriate ABS ring
– already correctly mounted
– precisely matched to the 17-inch geometry
This means ABS and traction control remain fully functional, without error messages or system interventions.
TÜV, DOT & Switzerland
– all rim rings have a DOT number
– this allows registration depending on the inspector
– for Switzerland, there are additional declarations of suitability
– clean, stress-free process
Who is the Supermoto conversion suitable for?
For you, if you:
– want more agility on the road
– ride sportily or track-oriented
– are looking for a more precise motorcycle
– want a significant visual change
– want a plug-and-play system with no tinkering
Especially owners of the 790/890 Adventure and the 1290/1390 Super Adventure are increasingly opting for the conversion.
Result: A completely new riding experience
With a tuned Supermoto wheelset, your KTM Adventure becomes:
– more direct
– sportier
– more stable
– more precise
– faster in corners
Many customers say that their Adventure becomes the best street bike they have ever ridden with this setup.
