Third-party tests of the Yamaha MT-03 indicate that it tops out at around 112 mph, with a 0-60 mph time of 5.1 seconds.
The MT-03 is one of Yamaha’s least expensive bikes and one of the most affordable 300cc motorcycles for new riders. It has an MSRP of $5,599 (including a $600 destination fee), which puts it ever-so-slightly above scooters like the Zuma 125 ($4,249 including $450 destination) and small dual-sports bikes like the TW200 ($5,374 including $375 destination fee) in Yamaha’s lineup. Affordability is often a primary concern for new riders, so the MT-03 addresses that concern right out of the gate. Even with the small price tag, though, the MT-03 is a pretty peppy bike. Yamaha classifies it as a hyper naked bike, right alongside some pretty impressive bikes like the MT-09 and MT-10, so performance hasn’t been ignored.
Yamaha doesn’t list acceleration or top speed numbers for their motorcycles, even the modestly powered ones like the MT-03, but sources say that the MT-03 will buzz from zero to 60 mph in 5.
