Worlds lightest street legal MV Agusta F4

I am going with this until I am proven other wise. I placed Mona Lisa on the scales. With everything on her, only no fuel, water, or oil. She comes in at 354.5 lbs. Here is how I weighed her. Scales at the drag strip I went to were not consistent and rounded off in 5 lbs. So I purchased a 2x10 board. Knowing that the scales I have go up to 440lbs. Placed the board on the scales, zeroed them, them rolled Mona onto the board. 354.4 lbs is what it read. So I am not 70 lbs under the stock bike. Not sure if I will be under the 400 lbs with all fluids topped off. But I am not sure where to save any more weight. I would of loved to been under the 35o mark dry. That would of been serious bragging rights.

So for those that don't know about Mona Lisa. The only things left stock on her is the dash and wiring harness.

I have every magnesium part available except for the engine cover which has the f4 on it, mine is the motocorse one. This means swingarm, frameplates, hub, lower triple, clutch cover, oil pan, gear housing, sprocket carrier, valve cover, and that thing on the top of the engine for the air pressure.

Over 300 Titanium bolts. All major ones on the bike and everyone that you can see. Only some left on the engine that I can not find the same size on. Full Bodis Ti system

Carbon everything. When I mean everything I mean it. I even had to have some stuff made for me. And yes the gas tank is carbon. Just look at the rotors. Less than a lb each.

Ohlins superbike forks weigh less than the stock forks on the bike. Then I had the Ohlins rear shock reworked to save over lb.

Most cast parts have been replaced with CNC parts. Most of them from Motocorse and a few others I also had made.

I even reworked the headlight to reduce weight and keep the stock look.

Removed the heat exchanger and added a oil cooler to the bike.

Went with the superleggera chain to save a lb.

Here is a pic of her from last year. I have not had a chance to get a good pic this year.

I have a problem leaving things stock. My MV has been my passion and I could not stop. With projects like these you throw logic and reason out the window. Look up stupid ways to spend money and you will see me and my Mona Lisa. But I did this for me. She makes me feel like a king when I ride her. It is unlike any other bike I have ever owned.

Guess I forgot to mention she has a 1078 engine hand built by the MV race dept using only the best OEM parts. Then I added some race cams to her. She has 184 hp to the rear wheel but should be more know that I lost a lb with the superleggera chain.

A real credit to you and your conviction for perfection.

Do you keep a running log of expenditure, or is it better to 'turn the blind eye'?

We know that non-enthusiasts will always say: 'You'll never get your money back on that.' But we do; it's returned ten fold in enjoyment! Cheers!!

Hi Andrew, I put this on your Facebook post, but if you are chasing every last lb have you looked at swapping out the battery for a lithium one?

Surely Andrew wouldn't overlook that? It's a 6lb saving straight off (as you'd well know). And dollar for dollar, perhaps the most cost-effective weight loss.

It's certainly a mod I will make when I'm next due for a battery.

Use too. But this has been a project going on for several years. Yes I agree in that you can not measure the enjoyment I get.
