stainless steel bypass for the removal of catalyst, fits in place of the catalyst, between the downpipes and the silencers. This version has been specifically designed for the Euro 5 Street Twins (with headers welded to the catalytic converter), Speed Twin 900, Speed Twin 1200 2021 (Euro5, type DD04) and Thruxton 1200 RS 2020+
You can reassemble your original silencers or Motone Odin and Saturn silencers
An integrated bracket to fixthe bypass on the frame avoids stressing the downpipes with too many vibrations, ensuring no long-term damage.
Unique construction in two stamped halves, which are then welded along the seam, contrary to all other models on the market which are made of bent tubes which are then welded.
- Performance gain
- Better engine sound
- Decreases the temperature of the engine, which results in a "rounder" performance and reduces the appearance of "bluing" on the downpipes
- no increase in fuel consumption as the engine mapping is not affected
- weight gain (2 kgs)
type A: Street Twin 2021 (Euro5, type DP04), Speed Twin 900 (2022+, type DP04)
type B: Speed Twin 1200 2021 (Euro5, type DD04), Thruxton 1200 RS 2020+
This change does not trigger the engine warning light as the O2 sensors remain in place (right off the cylinder head). You can also remove those sensors (with this kit) to facilitate cold-engine starts and idle, and simplify the bike's electrical system.
The original cat shield is re-fitted in place, which makes the modification invisible...
Fairly easy installation with basic tools.
Note: This change makes your non-compliant with the original bike, and as such it is not strictly legal for road use. The installation of this kit is your responsibility.
