Royal Enfield Rear Rider Seat Adjustment RAU00190 for Himalayan 450

Royal Enfield RAU00190 Seat Adjustment Rider Assy Rear is a genuine rear rider-seat adjustment part used in the seat assembly of compatible Royal Enfield Himalayan 450 motorcycles where this exact part number is specified. It is commonly searched as a Himalayan 450 rear seat adjuster, rider seat adjustment bracket, seat height adjuster, rear seat adjustment assembly, seat mounting adjuster or Royal Enfield Himalayan seat adjuster.

This part belongs to the rider seat adjustment system, helping locate and support the rider seat in its rear adjustment position as designed by Royal Enfield. It is a small seat hardware part, but it matters for correct seat location, rider-seat support, seat locking feel and overall comfort. A missing, broken, cracked, loose or incorrectly replaced rear seat adjuster can cause poor seat seating, rattling, uneven seat support or difficulty setting the rider seat correctly.

Royal Enfield parts references identify RAU00190/D as Seat Adjustment, Rider, Assy, Rear, and Hitchcock’s Himalayan 450 seat assembly partsbook lists RAU00190 as Seat Adjustment Rider Assy Rear with normal quantity 1. This listing is therefore written for the Himalayan 450 / 2024-on 450 Himalayan seat assembly where RAU00190 is specified.

Use this genuine Royal Enfield part only where RAU00190, RAU00190/D or the matching rear rider seat adjustment reference is specified in the exact seat assembly diagram. This is not the rider seat, not the pillion seat, not the front seat adjustment part, not the seat lock, not an O-ring, not a seat grommet and not a complete seat assembly.

Colour / Seat Variant Note

Hitchcock’s Himalayan 450 seat assembly page lists rider and pillion seat assemblies for different colour/model references such as Kaza Brown, Hanle Black, Kamet White, Slate Poppy Blue and Slate Himalayan Salt. The RAU00190 rear rider seat adjustment assembly appears as seat adjustment hardware in the same seat assembly section, not as a colour-specific seat cover or seat cushion.

Important Fitment Note

It is not the front rider seat adjustment part, not the rider seat, not the pillion seat, not the complete dual seat, not a seat lock, not an O-ring seat, not a grommet, not a seat support rubber and not a complete seat conversion kit.

Do not order only by the word “Himalayan.” Himalayan 450 and Himalayan 411 are different motorcycles with different seat assemblies and different part references. Match RAU00190 or RAU00190/D in the exact Himalayan 450 seat assembly diagram before purchase.

Do not order for Himalayan 411, Scram 411, Guerrilla 450, Classic 350, Bullet 350, Meteor 350, Hunter 350, Interceptor 650, Continental GT 650, Super Meteor 650, Shotgun 650, Bear 650, Classic 650, Thunderbird, Electra, Standard or Classic UCE unless the exact parts catalogue confirms RAU00190 for that motorcycle.
