Royal Enfield 1990504 Silver Large Engine Guards – Stainless Steel Crash Guard for Interceptor 650, Continental GT 650 & Bear 650 (Genuine GMA)

Royal Enfield part number 1990504 is the genuine “Silver Large Engine Guards” kit – a stainless-steel crash guard set designed by Royal Enfield GMA for the 650 Twin platform and Bear 650. The official GMA catalog describes 1990504 as Silver Large Engine Guards made from 25 mm stainless-steel tubes, offering an optimum balance of protection and style while resisting corrosion even when scratched.

On the Royal Enfield India GMA page, compatibility is clearly listed as Bear 650, Continental GT 650 and Interceptor 650, with a quoted fitting time of about 28 minutes, stainless-steel, silver finish. 

Most competitors only say “Silver Large Engine Guard 1990504 for Interceptor 650/GT 650” and skip details like 25 mm tube diameter, laser-etched Royal Enfield branding, corrosion resistance, warranty, and model years. This listing fills those gaps to reduce confusion and returns.

If you own an Interceptor 650, Continental GT 650 or Bear 650 (model years as per table below) and want serious crash protection with a factory look, 1990504 is the correct silver large engine guard kit to choose. For black finish, the matching part is 1990506 – Black Large Engine Guards.
