Interesting read, go to post 169 on the last page; What do they really weigh? | Page 9 | Adventure Rider
Klr's are far from light.....but sometimes they get unfairly penalized for things they offer that some other bikes don't....like 6 galls of fuel and decent range, a windscreen and a luggage rack.
I didn't weigh mine (might still) but from that link a stock Gen1 KLR with nothing added but a full tank of fuel is 399 lbs. I've weighed the parts for several changes I've made and I've deducted the fuel weight so comparisons are more accurate;
-36 lbs of fuel = 363 lbs wet, no fuel
I've swapped the silencer for an FMF Q4 (11.7 lbs for the stocker vs. 5.7 lbs for the FMF = another 6 lbs
I've swapped the battery for an LiFePo unit (10.8 lbs vs. 2.2 lbs) for another 8.6 lbs.
IMS tank; weight is close but the loss of the shrouds and related hardware....overall another 2 lbs.
I've removed the passenger pegs and brackets, factory toolkit, snorkle and cover, chain "guard", licence plate light and bracket etc...another 5lbs or so. ...then there are some mods that are likely "weight neutral" like the alum bars and handguards, my fancy hybrid rear sprocket, skidplate, etc.
I've added weight with the 320mm front brake rotor, adaptor and SV caliper (and it's worth every ounce! Didn't weight that one!
Overall my bikes ought to weigh in at about 345 - 350 lbs (wet, no fuel).....no lightweights but not bad considering a state-0f-the-art KTM 690 Enduro is 308 lbs and has a 2.5 gal tank, no windscreen, no real luggage rack and will never last 100,000 miles without engine work....
Every so often, someone goes nutz trying to lighten a KLR beyond the simple things I've done but even after they've stripped it down to nothing and it looks like a half finished bike, it never can be truly lightweight and the guy inevitably gives up, sells it and buys something else......with an engine that weighs 125lbs, there is only so much you can do!
