As I was putting my track bike build together, I kept track of the weight of stuff that got pulled off and stuff that got bolted back on. During the crash diet phase, we managed to shed almost 80 lbs off the bike. To get back to race-legal and to add the go-fast bits, about 35 lbs were added. Final weight is approximately 45 lb below stock. Provided for your entertainment

When all said and done, I will have lost about 18lbs from mine...
I could lose more, but mine is my street bike and I do NOT race...

Biggest weight-shedders are exhaust and battery (15 lb).
Smog pump/cali can -1.5
Aluminum sprocket - 1.1
That's 17.6 right there. After that, handlebars and rearsets is another 3 lbs


Refer to OP for break-down (basic math skills required)

I got my race bike down to 310 lbs with about a gallon of fuel in it. That was without trying to go to extremes to lose weight too, other than the 415 chain. Only reason I did the chain is because someone wanted my OEM chain and sprockets. Otherwise I would still have the OEM drive chain on. I would have changed the rear sprocket though.

Next year I am shooting for under 300 lbs though. Key less gas cap, Spears capture spacers front and rear, @jbluetooth doing my rear rotor, Galfer front rotor, an even smaller battery, aluminum fairing stay, and XT GPX Pro 8 dash/lap timer.

Ive got all my weights but they are metric.


Removed the side stand and its bracket
*Make sure you fit fat washers on the lower engine mounting bolt to take its place.


Can I just unplug the stand switch or do we have to bridge the wire?
Bike runs fine, but I want to take the entire switch off,
atmo I just cable tied it to a custom fairing bracket I made to take the sidestand plates place.

Yes and Yes.
Normally closed circuit - bridge at plug.
OP in grams so you should have similar values.

I had issues with the side stand switch. I pulled off the entire switch and just made a jumper. Otherwise the bike would shut off when I put it into gear. I had to do the same thing with the neutral safety switch and not wanting to start when I had the clutch in.

I am using an aftermarket clutch perch though. Hence the need for the clutch jumper.

How was it running after the the Smog pump/cali can removal? Any change?
