OVERVIEW 

17"  front and 17" rear spoked TUBELESS wheel kit to fit TRIUMPH 400 SERIES.
(SPEED 2024+, TRACKER 2026+, and THRUXTON 2026+) 
  
With the introduction of our new Gold-Anodised EXCEL TUBELESS spoked wheels, 
we are conscious that some owners may prefer a more visually understated appearance. 
We are therefore delighted to offer our same high-performance in-house designed 36 
hole billet aluminium hubs, laced with the same heavy-duty Bulldog stainless steel 
spokes, but in this instance to Black-Anodized EXCEL TUBELESS rims with an "Airtight" tubeless system with 2 years warranty.

Hand-built here in the UK, our "SPEED" wheelset offers a strong and reliable 
spoked wheel upgrade to the Speed 400S.
  
Each custom-built wheel kit consists of: 
Front wheel: 17” diameter x 3.00 wide, 36 spoke, Excel Tagaso aluminium rim, laced with heavy-duty stainless steel spokes and nickel-plated brass nipples onto our  own CNC machined billet aluminium front hub. 

Rear wheel: 17” diameter x 4.25 wide, 36 spoke, Excel Tagaso aluminium rim, laced with heavy-duty stainless steel spokes and nickel-plated brass nipples onto our own CNC machined billet aluminium rear hub - specifically designed to accept the OEM cush-drive assembly, and brake disc/ABS sensor components. . 
. 
 Both wheel sizes fit with OEM 110/70-17 & 150/60-17 tyre sizes.

TECHNICAL SPECS 

Both front and rear hubs are manufactured from 6082T6 billet aluminium alloy, and 
black xylan coated, for a durable finish. 
SMPro rims are a high-quality extruded aluminium rim and come powder-coated in 
classic Gloss Black for durability and ease of touching in any scratches if they ever 
occur. 
Heavy-duty "Bulldog" stainless steel spokes have 60% greater tensile strength than 
typicial OEM specification mild-steel spokes, and benefit from inherent corrosion  
resistance.  
  
Our spoked wheels are supplied ready to fit with new bearings and seals and accept 
all the OEM hardware to mount the rear sprocket cush-drive assembly, brake disc 
rotors and ABS sensor components. All you need is your own choice of tyres & 
tubes.

  
Our rim sizes (17"x 3.00'' front and 17" x  4.25" rear) were chosen specifically to 
enhance the on-road performance and all-round ability of the 400S, and allow a wide 
range of performance tyres to be fitted from any number of 
manufacturers.  
  
Benefits of our wheel kit 
• Rear hub is designed to work with the OEM cush drive and rubbers.
• Our rear hub/rim is 36 spoke pattern, much stronger and resistant to flex.
• Hubs supplied with bearings & seals.
• Both front & rear hubs designed to work with OEM discs, front & rear ABS rings 
and OEM screws.
• High-tensile "Bulldog" spokes are 33% larger cross section, and consequently 60% 
stronger tensile strength than the OEM plated mild steel spokes, plus they are 
corrosion-proof.
• Nipples are nickel-plated brass, again, corrosion-proof, maintenance free. 
Both rims are high-grade aluminium alloy EXCEL TEGASO, MT-type (tubeless 
specific) 
  

DO NOT USE ACID, OR ALKALI-BASED WHEEL CLEANERS TO REMOVE DIRT AND BRAKE DUST, AS THESE CAN CORRODE AND REMOVE THE POWDER-COATING AND TARNISH THE STAINLESS-STEEL AND NICKEL-PLATED BRASS NIPPLES. USE A PH-NEUTRAL CLEANER, OR SOAP AND WATER.
