LOL, just for fun I priced out some Ti hardware on the bike.

Thought I would first start with the large bolts M10 and bigger. They are primarily in the rear suspension linkage and shock. A rear axle nut because I've f'd up a couple axles already because of suzuki's locking nut design.
Then the fasteners on the rotating and unsprung locations. Rotor bolts, sprocket nuts.
I threw in the fasteners for the Sato race concept rearsets, too. They use 6 bolts on each side! a little overkill.

It came out to over $400!!! And could have easily been more. The caliper bolts and subframe bolts are drilled and seem pretty light already so I skipped those.


Waiting on some core moto wheels...

Weighed the bike in "road worthy" form. a crg mirror, small led headlights, taillight, side stand. and it stands at 380+#'s. I'm starting to obsess about weight but at this point the price to return ratio really sucks.

Finally got off my a$$ and installed the used Nomar into the garage floor.

I changed the tires out for new SP's. definitely can be a slight struggle until you get the technique down. didn't bother warming the tires up either. that would have helped. but, it beats the hell out of spooning them on.
I figure if I can change my car's tires then the unit will be worth it. As a matter of fact, not having to wait for service and driving there and back is "almost" worth it already especially bought used.


Weighed the bike in track mode- no sidestand, lights, track plastics and a full tank of gas- 380#'s. About 1/2 full it was 365#'s. Didn't know gas was quite that heavy. Although I guess oil and water(coolant) is even heavier.

I am waiting on some core moto wheels which should drop another 8 pounds or more. I just couldn't pony up the extra 1.5+ grand for carbon fiber. I may still get that race alternator.

Which axle nut did you end up with? I hate the OEM one as well. Would love to have some Core Moto wheels myself someday.

i didnt actually buy $400 in ti hardware, but i did get probolt's ti rear axle nut. not so much for any weight saved, but to avoid thsat thread eating locking mechanism of the oem nut.
i'll get a pic posted.

the core moto wheels are ~$2100. way better than the $4k of BST, at least thats what i keep telling myself...

Trying to remember which axle nut I actually have on mine now. Had one aluminum one but the anodized color wore off pretty quickly. Would like to find a good pre-drilled one.

Right. With my LighTech adjusters, the nut doesn't leave any axle protruding where I could drill and wire the axle itself and I really don't enjoy drilling the corners on the nut itself. The SV has a nice castle nut so you can just drill a hole in the axle and put a cotter pin through.

After waiting a LONG time, the core moto wheels finally arrived.
They look great, but all that matters to me is the weight and performance. (and price point/durability which is why I chose aluminum in the end)

Rear wheel measured against OEM with the same components installed (aluminum sprockets) is almost 4#'s less.

I still have to remove and weigh the OEM front wheel/tire.

I will spoon on some new Supercorsa TD's as soon as I find a supplier that has them.

Hopefully, after figuring out my tire wear issue, these will last more than one trackday...

Total weight savings 5.2#'s for the set. Not quite what I was hoping for, but 5 pounds of rotating/unsprung weight savings is nothing to sneeze at.
The OEM front is admirably light for a stock piece.
The core moto rear is impressive light.

With a 1/2 tank of gas, in track trim, I should be just into the high 350's to 360 pounds.
