Kind Code:
A1
Abstract:
A saddle-ride-type vehicle 1 comprises an engine, a rear wheel, a rear suspension 8, and a vehicle height adjustment mechanism 20. The rear suspension 8 is provided with a first spring 13 and a first damper 15. The vehicle height adjustment mechanism 20 is provided with a first pump 23a, a conversion mechanism 29, a hydraulic circuit 27, and a first jack 21. The first pump 23a is provided with a first cylinder 24a and a first piston 25a. The conversion mechanism 29 is linked to the rear wheel and the first piston 25a. The conversion mechanism 29 causes the first piston 25a to move relative to the first cylinder 24a due to the rotation of the rear wheel. The hydraulic circuit 27 is communicably connected to the first pump 23a and the first jack 21. The first jack 21 is linked to the first spring 13. The first jack 21 applies a load to the first spring 13 via hydraulic fluid supplied from the first pump 23a.
