Setup Note

Factory Baseline Included

Start with factory settings, then fine-tune for weight & roads.

The 66BHP Air Born Performance Suspension for KTM Duke 390 Gen 2 is built for riders who want a tighter front-end feel, improved braking stability, and more confidence over uneven Indian roads. With Rebound and Spring Preload adjustability, you can tune the bike for your weight, riding style, and load—without compromising everyday comfort.

Key Features

Rebound Adjustment (24 Clicks)

Controls how fast the suspension returns after a bump—improves traction, stability, and corner exit confidence.

Spring Preload Adjustment

Set ride height and support for solo riding, luggage, or a pillion—reduces rear squat and improves balance.

Performance-Tuned Spring Rate

Spring rate of 100.3 N/mm for a more controlled, sporty feel without harshness.

Made for Indian Road Reality

Better mid-corner composure on broken patches, improved stability under braking, and reduced bounce.

Tuning Parameters

Parameter	Total Range	Factory Setting	What it does
Rebound Adjustment	24 clicks	1 (baseline)	Slower return = more stability; faster return = more comfort on frequent bumps.
Spring Preload	5 – 25 mm	5 mm	Higher preload = more support (load/pillion); lower preload = plushness (solo).
Spring Rate	100.3 N/mm	Performance spec	Improves control under braking + cornering while keeping ride quality balanced.

Performance Advantages

More stable braking feel (reduced dive / improved composure)
Sharper and more predictable cornering
Reduced bounce and pogo effect on uneven roads
Better ride balance with luggage or pillion using preload
Confidence-inspiring setup for daily + spirited riding

Quick Setup Guide

Start baseline

Set Rebound = 1 and Preload = 5 mm.

For comfort

Reduce rebound slightly if roads are patchy and you want a plusher feel.

For load/pillion

Increase preload (within 5–25 mm) to prevent squat and keep handling sharp.

Night Rides Never Felt Safer & Brighter

I installed the 66BHP Valkyrie 4.5″ auxiliary lights on my Royal Enfield Himalayan before a long night tour, and the improvement in visibility was nothing short of impressive. Right from the first ride, the combined high/low beam and amber DRL made night riding more confident — the road ahead is clearer and hazards show up much earlier than with stock headlights alone.

The lights are robust and built well, and the IP68 rating gives peace of mind during monsoon and dusty conditions. Installation was plug-and-play with no wiring hassles. For the price and performance, this is a true upgrade for anyone who rides after dusk or in unpredictable weather.

Transformed My Highway & Touring Comfort

I’ve been riding my Interceptor 650 for long highway runs and weekend rides, and the stock rear suspension was always the weak point—too stiff on bad roads and unstable at higher speeds.

After installing the 66BHP Air Born Suspension, the difference was immediately noticeable. The bike feels more planted on highways, cornering confidence has improved, and bad patches are absorbed much better compared to stock. The adjustability actually works and allows fine-tuning based on riding style and load.

Installation was straightforward, and build quality feels premium. This is not a cosmetic upgrade—it genuinely improves ride comfort and control, especially on Indian road conditions.

If you tour or ride aggressively on an Interceptor or GT 650, this upgrade is worth the investment.
