“The high-tech sys­tem is a ver­sion of what we’ve al­ready seen on the firm’s R6 and R1, which op­er­ates the mo­tor’s vari­able valve con­trol, fuel in­jec­tion and cool­ing sys­tems.”

This is the 2019 Yamaha YZF-R 125 – a land­mark small ca­pac­ity mo­tor­cy­cle that’s go­ing on sale as the first 125cc bike to fea­ture vari­able valve tim­ing.

The high-tech sys­tem is a ver­sion of what we’ve al­ready seen on the firm’s R6 and R1 which op­er­ates the mo­tor’s vari­able valve con­trol, fuel in­jec­tion and cool­ing sys­tems. The bike also gets a new swingarm and re­vised ge­om­e­try to make it more sporty.

The VVT sys­tem means more midrange power when needed with­out sac­ri­fic­ing any of the top-end fun that’s so vi­tal a com­po­nent of the small bikes.

There’s also a new LCD dash with gear in­di­ca­tor, the seat has been re­designed and the 11 litre petrol tank re-sculpted for a more sporty rid­ing po­si­tion.

Called the Vari­able Valve Ac­tu­a­tion Sys­tem, the set-up is dif­fer­ent to the in­ter­mit­tent when run­ning Honda V-Tec set-up. With the Yamaha the VVA sys­tem is al­ways op­er­at­ing when­ever the mo­tor is run­ning, giv­ing the best valve po­si­tion pos­si­ble for any par­tic­u­lar speed or de­mand on from the rider.

The mo­tor also gets a new cylin­der head with larger di­am­e­ter valves and a smaller com­bus­tion cham­ber to im­prove com­bus­tion.

There’s a short­ened swingarm bolted to the Deltabox frame, the new forks are 41mm units and the rear tyre is now a 140 sec­tion to im­prove sta­bil­ity. The bike is be­ing sold in black, blue or white colours and will be in deal­ers early next year.
