Weight Reduction / Weight Of Components

All weights are in grams. I'll add more figures as stuff comes off...

Standard Seat = 2105
Rear Hoop + Bolts = 2544
Passenger Pegs + Bolts = 1860
Radiator Sides + Bolts = 655
Side Reflectors = 130
Peg Feelers = 40
Tank Outer Shell Right = 736
Tank Outer Shell Left = 736
Tank Outer Centre = 348
Tank Inner Centre = 406
Tank Shell Bolts = 88
Tools = 99


I've managed to shed 5kg by removing the above (not including the rear hoop and seat).

I plan to get the single seat and shave it over 50% so depending on the weight of the single seat that should be close to another 3kg. On top of this 3kg we can add the weight of the original tail which I will weigh once it comes off.

Beyond this I'll be looking at lithium battery which is good high weight even though it wont amount to a lot. A change of headlight will yield a small weight saving as well.

Let's not forget the exhaust which can yield up to 5kg but the one I'll be going for will only yield a 2kg saving.

I also fill up a large jerry can of fuel which I use to top up the bike at home so I only run half a tank at the most. This is another 7kg saving at least.

With all of the above I should be in the mid 160kg range or roughly 20kg lighter than the advertised wet weight of 186kg.

The above is all easy weight reduction that I've identified in the last couple of days of owning the bike. Keen to hear more ideas from you guys.

A little bit more work, but you could replace the air box by simple filters:



The modification is said to be well handled by the stock ECU.

Notice that the side cover near the footpegs got removed also.

I didnt weigh the akra before I installed it but it seemed about HALF the weight of factory one using the scientific one in each hand test. It must the way the weight is distributed in the exhaust canister design cause I figured it to be 3.5kg but the spec says its 5.7kg..........take out the baffles and theres 15g shed :grin2:

Thats gold ! the airbox/filter would be 1.5kg.

You could take it a step further and make two scoops like on the Vmax and you have......Ram-air induction ;)

Akra website says the weight gain with the 2016 exhaust (with the carbon out-sleeve) is 1900g. I think you would have too add the weight of the catalytic converter to make it street legal.

Ain't it too loud without the baffles?

This is epic. Love to see serious weight reduction builds or rather "de-builds" going on. Can't wait to see the end result on this.

It's the "Onyx Blade" by Rough Crafts, based on a MT-07. I can't tell you much more.

Adhoc café racer did the same king of job with the "Otokomae".
