correct me if i'm wrong, aren't the 150s air cooled and the 250s water? That would be where most of the weight difference comes from, coolant/hoses/radiator etc..

2007 Sunl SLGK-250-2A-2 GK-10 cn250. I drove mine onto the truck scales at my plant. Gross weight with gas and oil, 660 pds.

Dry weight 498lbs,full fuel and oil 512lbs with out driver,647 with driver meaning me.No mods-stock only.mancoman

Who makes the lightest weight two seat 250 out there. Off of manufacturer claims it looks like hammerhead line is pretty light. Just curious if any brands are weighing in less than the HH line.

My turbo 150 cc coolster weighs 508 ibs wet with out me in it.
i believe they also go by the name challenger.

the turbo kit probably added a few ibs , but the stock exhaust was also pretty heavy and thats gone now.
