I have a GR150 and I warn you that it's heavy. If you are planning on off roading you better have some good arm and leg muscles to handle the bike. Also gr requires more maintaince and modification to be used as touring.
1. You HAVE TO replace the manual carb with the CV carb from GS150 as it's better for high altitude.
2. Gr chain require way more care than any other bike. It gets loose after 200 km 🤷..
3. Gr ka engine generates a lot of heat so you better install an oil cooler as it has the option to in the engine.
GR has a huge engine advantage as the engine makes its peak torque in mid rpms Soo better for off road
