블로그 약 Guide to Kews Highperformance Offroad Motorcycle Platforms and Configurations

The Kews off-road motorcycle lineup is built around a flexible engine platform strategy that spans four-stroke and two-stroke powertrains, from entry-level models to competition-oriented machines. Its four-stroke range draws primarily on Zongshen powerplants from 250cc to 450cc, while the two-stroke range follows three separate technical routes. The following breakdown covers the engine options, Enduro model matrix, and key specifications for the Zongshen CB250-F.

Core powertrain platforms and engine options

The Kews range’s engine strategy centers on adaptable powertrain sourcing. For four-stroke models, Kews works primarily with Zongshen Power and covers displacements from 250cc to 450cc. Those engines can be supplied with either carburetor or electronic fuel injection systems to meet different emissions rules and rider preferences.

The supported four-stroke engine designations include:

• CB250-G (ZS165FMM)
• CB250-F (ZS172FMM-3A)
• PR250 (ZS172FMM-5)
• CB250-R (ZS172FMM-6)
• CB-F300 (ZS175FMM-3A)
• PR300 (ZS175FMM-5)
• CBS300 (ZS174MN-3)
• NB300 (ZS174MN-5)
• NC250 (ZS177MM)
• NC250S (ZS177MM-A)
• NC300S (ZS182MN)
• NC450 (ZS194MQ)
• NC450S (ZS194MQ-2)

Kews also plans to add the NC250RR and NX300 four-stroke engines in the future. On the two-stroke side, the lineup uses three technical routes: the Loncin MT250, based on the Yamaha DT architecture; and the MLF 250cc and 300cc engines, based on the 2018 KTM architecture. The two-stroke models are currently offered only with carburetor fuel delivery.

Enduro model matrix

The Kews Enduro range is positioned to cover different competition and recreational needs, with eight core models. Each model is mapped to an international mainstream off-road platform as its design and structural reference.

• K16 (KTM 2017)
• K18 (HUSQ 2018)
• K19 (Honda 2016)
• K20 (KTM 2019)
• K21 (Kawasaki KLX)
• K22 (HUSQ 2020)
• K23 (KTM 2023)
• Rally 450

Beyond the standard Enduro models, Kews offers off-road models in multiple specifications. Standard colors are orange, black, and white; custom colors require a minimum order quantity of 100 units.
