Hammerhead 250F
The Hammerhead is a motocross bike you can buy from the junkyard. After a small amount of progression through Jake's questline you will get an email from Johnny Junks stating that he has a salvageable motocross bike.
The Hammerhead costs $1200 and does not have an engine. The 250cc engine parts can be found in the junkyard and you will likely need to check back on different days to get all parts. The frequently serviced parts(head gasket, cylinder, piston, and clutch) can be bought at New Age Auto Parts.

Maintenance
When the bike begins to lose power, it is best to replace the head gasket, cylinder, and piston. The clutch should be replaced if the bike still lags after a top end rebuild.
Fluids and oil need to be refilled after opening the engine case.
