Montesa 4rt Engine Weight

Featured Replies

Have been searching and come up with nothing.........

So, has anyone put a 4rt engine on the scales?

Ha! yes heavy kgs I reckon

Never had mine fully out of the bike or I probably would have done that just out of curiosity.  Hopefully someone has and is willing to post it up here.

We have a couple laying around work. If I remember to bring a scale from home I could weigh it Monday. Probably 80 lbs.

There's a reason that Bou and Fuji's motor cases, covers and fuel injection body are built by HRC out of magnesium....

Read an article once all about Bou and Fugi's bikes but couldn't find that one.  This is at least an official link to Honda Racing so shows that 4 gears is defiantly the case and if I remember correctly 314CC.

 Ha I found this post again this a.m. So I just happen to have a complete motor my boss gave me last night. It was pulled straight off the frame, so it still has the radiator, wiring harness, clutch master cylinder and all levers. Shows 68 lbs. so around 64 lbs motor only.
