Picked up a new '19 GS in the middle of last year and loved it. Having ridden a Triumph Bonneville SE for over 50K miles, I definitely missed the acceleration coming down to a 300.

Looking at the bike, there are quite a bit of simple things that can be down to drop almost 25 pounds. This was exactly what I did and now the bike is a little ripper!

Note: I calculated the weight loss by weighing myself first on a bathroom scale followed by re-weighing myself on the scale while clutching the part as close to myself as I can.

-Akrapovic Carbon Exhaust -10 pounds
-EarthX ETX18F lithium battery -5 pounds
-Passenger footpeg bracket removed - 5 pounds
-SWMotech Alu-Rack (Chinese knockoff for G310R but fits GS just fine) - 3 pounds

Total weight wet: approximately 351 pounds

Here are some pictures of the parts. To remove both the passenger footpeg mount, I ordered a pipe bracket for the G310R off Amazon. I did have to dremel a small piece of the plastic off the GS tail section but it is barely noticeable. I can't post a link onto here, but if you search for "G310R Accessories Exhaust Muffler Bracket Hanger Holder" on Amazon, you should find it!


Calculating the power to weight ratio, here's what I get:

Stock 374lbs / 34 hp = 11lbs/hp
Current 351lbs/ 34hp = 10.23lbs/hp

Calculating HP gain from weight loss:

374lbs/(10.23lbs/hp) = x
X = 36.55hp
Net gain of approximately 2.5hp from weight loss.

Here are some pictures of the parts. I can take better ones when I have more time later on. If you have any questions, please feel free to ask!

Unfortunately that's not how it works, you don't gain any HP by removing weight!
You're correct, but he's not claiming to have obtained more horsepower overall. The horsepower figure is the same in both calculations. however, by reducing overall weight the result is more horsepower per pound. The mathematics are straight forward and are correct as well. 0:)

Thanks Arion! Your explanation is exactly what I meant.

To avoid misinterpretation, I should've stated that the performance gains from dropping that weight would be equivalent to a hypothetical G310GS with 36.5hp pushing a wet weight of 374lbs.

This thing is a riot to ride with that weight loss. As Colin Chapman once said, "adding power makes you faster on the straights. Subtracting weight makes you faster everywhere."

This is super helpful. The weight you listed for each item, that’s how much weight you saved compared to the original part? Do you know the original part weights? I can’t find them all

I have a Jeep rubicon with 350 max tongue weight to carrier tow. The 2022 is 362 wet, plus 35 pounds for the carrier. So I basically need to lose 47 pounds.

3 gallons of gas = 18
Removing exhaust = 15
Passenger pegs = 5

38 pounds right there. 18 more to go

Batter?
Rack?
Anything else?

I only have to tow this when I’m towing my Jeep behind our Motorhome. Every 3-4 months. So it’s not a big deal to spend an hour removing everything so I can get the bike that I’m jazzing for.

Any suggestions would be amazing

Also you can change the handlebars for an alloy ones, saving some weigth and best handling, also I changed to spoked wheels and makes the bike limber.

Can you explain a bit more about the rack option? I'm a bit confused. Is the SW Motech part made in china? Are you somehow eliminating the stock rack that comes with the bike?

as most of the folk in the developed world are over-weight.
the most dramatic weight loss is for the rider to shed several pounds/kilos ;-)
as a bounus health will be improved..!
