2015 klr weight loss program

i love my 2015 klr650. got it july 27, and even with all this rain in florida--and a riding schedule restricted to saturdays--i have over 1100 miles on it. so, heres some hard data: 8 pounds 5 ounces of weight loss thru removing the rear lower fender, passenger footpegs, and luggage rack.
what a great, usable bike!

You can lose about 4-1/2 pounds from the rear tire and 2-1/2 from the front by going tubeless. Muffler is heavy but very pricey for the small weight loss.

Holy Crap, Normk!
What brand of Super Heavy Duty rear inner tubes do you use and WHY? If it is long enough / sharp enough, it is Still Going to be FLAT. Thinner tubes actually run Cooler on asphalt.

Using a common bathroom scale, and holding/not holding an IRC 4.00/5.10-17 rear inner tube (standard duty) in my hands, I measure between 1.5-2.0 pounds, including the Box!

A customer/friend (Clark with the 100% oil filtration mod) of mine showed me his $100 USD Leo Vince Exhaust Muffler, this very afternoon. Used/UNUSED from Ebay, recently. Two little dents in the tail cap. Complete with different louder cores and USFS spark arrester screen. Quiet enough that I'd spend a hundred, for used/Unused.

i am very interested in the tubeless conversion. i raced mountain bikes for years and learned first hand the difference wheel weight makes, especially weight out at the rim! not only unsprung, but also rotating mass. i still remember when i switched to tubeless on my race bike the change i gained in acceleration and handling was noticeable, and i already had a very light (by tube-type standards) wheelset and tires to start with.

lithium battery weight savings is much more than i realized, i will make the change next week.

Paul, I weighed the wheels with tubes, rim strips and tires, then compared that to the wheel with spoke sealing, tubeless tire stem and tubeless tire. As I recall, the difference on the rear was 4-1/2 pounds and something like 2-1/2 on the front. A friend who did his wheels agreed with the numbers.

That said, I may have miscalculated and perhaps he was subject to confirmation bias. I will try to remember to gauge the weights when I change the rear tire for a new one. Given the distances I'm riding these days, that could be quite a while. I'm not committed to those numbers but, as sshbsn stated, the effects were very noticeable.

I'm sure Norm is right (Hi Norm :-) ) but you're right, the tubes by themselves don't weigh anywhere near that much.

Personally, I prefer tubes but I have an offroad bias and background.

The "low hanging fruit" of KLR weight loss;

- battery; my LiFePo weighs 2.2 lbs compared to over 11 lbs for the stocker....a no brainer with no real downside

- silencer; my Q4 weighs 5.7 lbs compared to the stocker at just under 12 lbs.

- IMS tank; while the tank isn't much lighter, you loose the shrouds and hardware and it offers decent rad protection without adding bars....approximately 14lbs difference.

- misc. bits that aren't strictly required for most people; passenger pegs and brackets, sidestand safety switch and all related crap, snorkle and cover, etc. I haven't weighed everything I've removed but it's another couple lbs at least.

other ideas; the stock tool kit is heavy and not very good....you can do better. I've also lost a tiny bit with my billet alum footpegs and a few other parts but after the stuff above, it becomes an exercise in diminishing returns......people that have really tried to make a light KLR typically strip it down to something that no longer resembles a complete motorcycle only to find that a KLR can never be truly lightweight.....the engine alone prevents that.

Oh, and only take the fuel you need (plus a bit extra for safety); you don't need 6+ galls for a 100 mile ride.

Cheers,
Dave

wow thats a comprehensive list! thank you. i appreciate your endorsement of a specific battery brand. internet research made me uneasy about choosing one.

im building this to be a modern replacement for my beloved xt500, sold in a fit of stupidity for equipment i needed on a jobsite. i intended all along to get a dr650 or the ugly beemer, but somehow during months of reading and many trips to the dealerships i ended up getting the klr. im EXTREMELY happy with it. it handles worlds better than the xt, but lacks the excitement of plan-ahead braking and hot-rodded engine (a good combo). the klr will never carry a passenger or cross a desert while i own it, so i might as well "add lightness" as colin chapman said.

im also surprised at how good the headlights are on the klr. a great quote about the 6v xt500: "a headlight so dim a moth couldnt find it". the kawasaki lights up late night country backroads much better than i expected

Actually that's a type of battery rather than a brand; I use Antigravity batteries HOME • Antigravity BatteriesAntigravity Batteries | Lithium Ion Motorcycle Batteries but I've also heard good things about Shorai's. Home - Shorai Lithium Batteries
