If you were to throw everything listed below in a box, does anyone know what it would weigh? Not looking for an exact weight but within a pound or two would be nice.

BDX diamond lite drive
BDX lightweight rotor & pads
BDX lightweight track shaft with drivers
secondary clutch
brake caliper with bolts
track shaft nut

Under 30 lbs? 25 lbs? 20 lbs?

Thanks

I managed to find a few of the weights in old posts.

Diamond Lite drive is 13 lbs 5 oz.
BDX lightweight brake rotor 1 lb. 10 oz.
BDX pads for ceramic rotor 10.5 oz.

Anyone know how much the lightweight trackshaft weighs?
Brake caliper?

I weighed the ddrive, trackshaft and rotor when I put them on this summer. The trackshaft was dead nuts the same weight as the stock shaft and the complete brake setup (pads, rotor and little spacer ring) was 2lb9oz lighter from BDX. The BDX diamond drive was 3lb lighter than stock, no oil. Sorry - I don't have notes on the original weights anymore, just the weight savings but the numbers I listed above are very accurate.

Also, the savings are being compared to a 2011 m8 above.

Guessing he means the recoil cage with TI bolts. The nut is same as stock... unless you grind some off before you install (joking... joking)

I meant the brake caliper that mounts to the chassis.

I've never seen this part from BDX. You can get the caliper BEARING from them, but as far as I know they don't sell a light weight caliper.

I know this, I was looking for the weight of a stock caliper. Sorry for the confusion.

I have two used calipers on the way. When they get here I'll throw them on the digital scale. I was just curious as to the complete weight of a Diamond Drive setup compared to the CMX belt drive.

Does the 07 M8 recoil kit fit in the M7??? Just out of curiosity...or are they different recoils?

Cat parts are portly. A complete brake caliper with nuts, bolts, spacer, bearings, but no pads is 4.6 lbs or 4 lbs 9.5 oz. So 20 lbs 2 ounces for everything except the clutch and track shaft with drivers which I don't have to weigh.
