REINFORCED. RELIABLE. REIMAGINED.

Strength added where the original geometry is most vulnerable

GEN II was reworked around the mounting bracket, cylindrical sealing flange, elbow transition, and wall thickness while retaining the original installation layout.

01

Thicker Walls

Increased wall thickness through the elbow provides more material in the high-stress flow path.

02

Reinforced Transition

Smoother internal and external transitions distribute mechanical stress more effectively through the bend.

03

Stronger Mounting Bracket

A substantially reinforced mounting structure improves support around the single-fastener interface.

04

Robust Sealing Flange

The cylindrical engine-side flange is strengthened for a secure O-ring interface and long-term durability.

COMPLETE GEN II KIT

Everything needed for the replacement component

  • Qty. 1 GEN II high-temperature coolant sleeve elbow
  • Qty. 1 Class 12.9 socket-head fastener
  • Qty. 1 flat washer
  • Qty. 1 high-temperature O-ring seal
  • Installation instructions

The supplied Class 12.9 fastener is pre-coated with blue thread-locking compound to help resist loosening during normal motorcycle operation.

Important: This is a cooling-system component. Work only on a completely cool, depressurized engine. Correct O-ring seating, fastener practice, hose routing, clamp placement, coolant refill, air bleeding, leak inspection, and post-installation monitoring are essential.

GEN II DESIGN

Purpose-built rather than simply copied

The revised geometry concentrates reinforcement around the areas most exposed to mounting load, vibration, hose-clamp pressure, heat cycling, and impact.
