| They're probably talking dry weights. The WR-250R is two-seventy-something pounds dry. Dry means with no fluids in the bike, like gasoline, oil, coolant, etc.
The weight figure you read today on the Yamaha website or the 2010 model brochure now shows a wet weight figure, with gas in the tank, oil in the engine, coolant in the cooling system, etc. | |

- The WRR weighs 300lbs stock right? Where is the 25lb number coming from?
Wr250R is 276 lbs. dry vs. 251 lbs. dry for a KTM 450. A quick search confirms the KTM's weight is dry. Add fluids and they both increase about 20 lbs. I do not know when Yamaha switched the WRR specs from dry to wet weight. When the bike was first released, the website listed the 276 lb. dry weight. For the record... my friend races enduros [very] competitively with the KTM 450. When we switch bikes, he eats my lunch in the woods. In other words, his advantage over me has little to do with his KTM. | |

From a dead stop I smoke my friends 450... and his top end is to low to get me.. Ok so it may be me I smoke DL1000's on my DL650 as well Sometimes less is more.. I may have less power on both bikes but I can put that power down without the bike getting away from me and get moving a lot faster... Once going the WR has the top end with gearing... Once going the 1000's will pass me but by then I'm doing 80+.. Like NJbill said with his friend it's not always the bike, it's more the rider.. | |

| OK, so does anybody know what the big hitters are for the extra weight on the WR250R/X vs. the WR250F? I suppose the counter balanced motor, steel cradle frame, additional rear framework, steel tank and added DOT bits are probably the big hitters, but it would be interesting to know what the break down is. | |

| Hi
I sent Jim (the owner of Eastern Beaver) a picture of the plug required to bridge out the wiring when the side stand is removed. (to save chopping the cable) He replied with the info it is a 'regular' 2P090wp-MT connector. (not a Special version) Female part is $1.95 Plus shipping.

| My son and I changed the oil on our bikes today. First oil change on his used bike. We both have Flatland skid plates and we found his was drilled out to make it lighter. I used the wifes kitchen scale to check and the difference is about 5 ounces. Do you think 5 ounces down that low will make much of a difference? | |

No, but the improved air flow and resulting cooling will. The holes in my Flatland are the large original ones on both of yours, but I had them add them across the front. | |

| I am glad there is a weight loss thread for the WRR's. I rode mine to work today...one, to see how I like it on the road for longer than 3-5 miles at a time and how much it weighs. I have pallet scales here at work, and I can get the whole bike on there and not have to any of that front Wheeler/back wheel guessing game crap.
I also only believe in talking in wet weights, since that is how we ride the bikes. Dry weights, are often inaccurate from one make to another, and just a marketing tool. Useless.
Anyway, at this point, I have removed stock mirrors, counter sprocket plastic guard thing, rear passenger pegs, and reflectors. Stock tires and tubes also replaced.
I have installed Flatlands skid plate, Ivans case saver, and Moose bark busters with handguards. Pirelli XCMH tires installed with heavy duty tubes. Rear was ultra heavy duty and weighed a good bit. Also installed a 120/100 rear, instead of the 120/80 rear...did not realize I ordered the wrong size until I had mounted. I mistakenly thought they ran the same size tires as the DRZ 400's. Will fix with next tire swap.
Bike probably has about 3/4 tank of fuel.
299 lbs. I was hoping for more...but such is life.
I am planning on the flapper mod and AIS system removal ASAP. | |

| Another bump of this thread.
At a recent event I took part in, one of the guys swore that he got his WRR down to 262 lbs. I do not see how that is even possible?? He did say his used a truck scale that went in 38 lb increments..which makes no sense anyway...but I am thinking it was 262 plus 38( one increment off) and really more like 300 lbs.
In road ready mode, as I had mentioned in last post, lowest I could go was 299 lbs. That was still with hand guard and skid plate, lights, etc.
For a more recent event, I took off all street needed stuff, rear lights, plate, plate holder, head lights, blinkers, etc, and only took off another 7 lbs..putting it near 292 lbs.
I don't care about dry weights, or theoretical weights, or truck scales( % error range on those is greater than total bike weight) weights..I just wanna know, with accurate scales, what the lowest actual weight anyone has gotten. if you know about of gas in bike, that would help too..since gas weight can be factored in.
Thanks. | |

| From my website:
When I got my WRR home, the first thing I did was weigh the bike and take measurements. I drained the fuel tank so I could get the empty weight; the WRR weighed 280 pounds. If you look at the Parts removed list at the bottom of the page, you'll see that I removed about 20 pounds of parts during the course of doing my mods. I then added back about 5 pounds of new parts, yielding a net loss of about 15 pounds. This puts my WRR at around 265 pounds, ready to ride with no fuel.
A gallon of gasoline weighs 5.93 to 6.42 lbs (2.69 to 2.91 kg), depending on temperature, type, and blend (e.g. with methanol, water, benzene etc.). I filled the fuel tank with premium, non-ethanol gas until it was full and even burped it to get the max in that I could - 8,100ml or 2.13 gallons. Using 6.25 pounds per gallon, I get about 13 pounds for fuel giving 278 pounds for the bike, ready to ride with a full tank of gas.

| Rick, thanks for the reply. I took off most of what you took off, and probably got 80% of the weight savings you did. I did leave on the stock blinkers and tail light assembly, as well as the side panels. The blinkers, although big and bulky, are a really good design and really robust. My bike has seen hundreds of drops and other than one bulb itself imploding, they have held up great. I did have one of my rear ones snap loose and fall on the exhaust can..still works, but needs replacing.( I just got in spare parts from another member). so, 299 that I got on a pallet scale, minus 13 lbs of gas at a roughly full tank, is 286 lbs. Race ready, 286 lbs, minus 7 lbs for lights, blinkers, etc, still yields 279 lbs, with no gas. I am gonna bring it to work again soon and see how much it weighs with no gas..not that the bike can be ridden with no gas. | |

| Currently I've added 6 lbs. to my bike's overall weight (can't stop eating more during the holidays). I'll be taking that 6 pounds off the bike next year! | |

Hey, wasn't that a question on the GRE post grad admissions test? Or SATs in sixth grade? Back on topic... I replaced my front brake line lower clamp (unsprung weight) with two plastic cable clips fastened with mini zip ties. And does anyone know the weight difference between the aftermarket 3 gallon poly tank vs the stocker? | |

- Anybody got details?
Their motor is probably a lot lighter and their frame is lighter. Their motor is built to win a few races, not last 50k miles. Our motors require probably 1/10th of the maintenance. Also, our frame is built with the knowledge that a person might ride on the bike and there might be luggage attached. They also lack basic things you have to have on the road like... a kick stand, blinkers, mirrors, speedometer, license plate and brackets, catalytic converter, etc... | |

| Anybody know the weight difference in wheel brands? I have warp 9 and they seem like they have the light hubs but they have heavy spokes. Also some more weight savings ideas for those with precision instruments: Misc. aluminum farkles like: water pump cover, oil drain plug, wheel spacers, etc. Great thread! | |
