Intruder Lineage:
The Intruder series established Suzuki in the cruiser market, known for its V-twin engines and distinctive styling. The VS700 was the initial model, followed by the slightly larger displacement VS750 and the further refined VS800. The VS800's platform was later evolved into the S50 Boulevard, continuing the cruiser tradition with modern updates.
Initial Production Vs700:
1985
S50 Transition:
The VS800 was rebranded as the S50 Boulevard in 2005 as part of Suzuki's larger Boulevard cruiser line, receiving some styling and minor mechanical updates, but retaining the core engine and chassis architecture.
