BNJ 2026 GP4 World Champion Model – Yamaha SuperJet SJ1050 / SJ700 Front Sponsons

The latest evolution in BNJ front sponson design. Developed for championship-level handling and now available to the public.

Introducing the BNJ 2026 GP4 World Champion Model Front Sponsons, developed specifically for the Yamaha SuperJet SJ1050 hull and also suitable for Yamaha SJ700 models with the 2008+ hull design.

Featuring a unique billet construction and a substantial 3.54 kg weight, these front sponsons are designed to deliver increased hull grip, improved stability, and enhanced handling. Their added weight is intended to benefit the heavier SJ1050 hull, while offering a potential handling improvement over other front sponson designs on later SJ700 hulls.

Developed through dedicated testing and competition experience, this is BNJ’s latest handling-focused front sponson design.
