Honda MVX250F
Encyclopedia
The Honda MVX250F motorcycle was developed by Honda. It was powered by a two-stroke V3 engine.
New Zealand was among the few countries in the world outside Japan where the MVX 250 was sold new through Honda motorcycle dealerships.
In 1984 the MVX 250 was sold new for $3299 New Zealand dollars.
Initially many bikes suffered engine failures, often within the warranty period. Honda released a number of engine upgrades including a larger rear conrod to address engine balance issues in an effort to improve engine reliability. After prolonged periods of full throttle many engines suffered piston failure on the rear cylinder. There is much anecdotal evidence to suggest that incorrect ignition timing was the cause of piston failures and subsequent engine seizures.
However, probably due to the model initially experiencing mechanical failure, changes were made to the rear cylinder. The conrod, small end bearing, and piston were revised.
Also, the head gaskets (may?) have been modified to allow for better coolant flow to the rear cylinder.
The engine sits in the frame with the two outer cylinders facing horizontally forward and the rear cylinder facing vertically upward.

Models
There is only one model.However, probably due to the model initially experiencing mechanical failure, changes were made to the rear cylinder. The conrod, small end bearing, and piston were revised.
Also, the head gaskets (may?) have been modified to allow for better coolant flow to the rear cylinder.
