Lowering Radiators XR650R

22 posts in this topic

I read in one of the dirt bike mags that lowering the radiators 2 1/2 inches lowered the center of gravity on the YZ450F. All the riders of the test bike noticed the difference and liked the handling. The magazine is the August Motorcross Action. The lowering was done by PWR a custom radiator shop (Clint Barry owns the shop)

I looked at my XR650R and it looks like you could lower the radiators. It will require some new brackets and mounts. I would like to put Ms Piggy on a diet but lowering the center of gravity would also make the bike feel lighter.

The magazine is the August Motorcross Action.

The Harry Potter series of books has more useful information about bikes than Motocross Action Magazine.

The name Irondude is synonymous with the XR650R. It has a deep reaching meaning that signifies rock solid, never die, and always finishes the race.

If you are going to post your Husky trash on this forum, than please use an alter ego name such as; ButtPirate, TurdBurglar, ChocolateStar, or some other name that will identify your personality with the other Husky riders. (maybe brrpr)

I would like to thank everyone for all of there technical :applause: input.

Sorry bro, just messin around.

Do you really think that the spodes over at MXA could tell the difference in a bike that has it's rads dropped two inches? What a joke.

How much coolant/fluid does the 650 hold? Maybe 1.5 liters? Only half of which is in the rads.

If you carry 1 less gallon of fuel in your tank, you should notice a HUGE difference then, right?

Cancel your subscription to MXA, and spend the money on booze and porn. You will be much better off.

Though i agree with the booze and porn suggestion :applause: i think that lowering the radiators would be noticable. i know that many dez racers such as 1X dont run fluidynes not rad guards because of top heaviness. it really makes a difference. You do notice a difference when you're allmost out of gas dont ya. My bike handles way differently.

That being said- The 650 is not for all, you must appreciate its strong points and be a strong enough rider to get it through the rest. Lightness is not a reason for owning a pig(unless you came herein a time machine from the past and only rode BSAs":D

i can barely notice a difference when i leave a pit with a full tank of fuel VS 50 miles later when i have burned off 2 gallons....2 gallons equals 12+ lbs! If 12 pounds is only slightly noticable--its hard to imagine that 1 pound of weight for radiators is really going to be that noticable...

If you run 12 psi VS 17 psi you have WAY more than an extra pound of air...

i run the fluidyne --at most it adds 1 pound with the fluid. i am no steve hengveld--thats fersure--but i just cant feel anything. of the half dozen or so guys who ride 650's and who have jumped on my bike--none have ever said anything about the weight of the fluidyne radiators--although they give me a hard time about other stuff!

if its weight savings ya need--go to the gym and lose 2 pounds.

ps---any takers?! New No Toil Airfilter....

You can't get anyone to help you Wolfdude....because they all agree with me. :eek:

I checked with the owners of TT, they said that the name "HuskyDNF" was still available, if your interested. :applause:

(No disrespect meant towards Mr. Schmuckle) :)

I would have to disagree, I recently read that Honda has tilted the 06 450 motor 5 millimeters downward to achieve a lower center of gravity. While a motor is a lot heavier than rads 5 mms isn't much. I would think that to get a lighter feel on a 650 all the normal mods would need to be done plus innovative one's such as lowering the rads. Of course one could also just get a Husky and be done with it. :applause:

I would love to get that free filter but don't want to rip on someone I don't know, plus I don't take bribes, haha.

Too bad the techs at Honda don't read MXA....they would have known to just lower the rads 2" instead of tilting the engine 5mm. :eek:

(I'll bet the engine tilt has to do with the new valve configuration.)

(What valve problem?) :applause:

If you are really serious about lowering the center of gravity get a Kouba lowering link. Lowers the rear of the BRP approximately 1-1/2". You lose a little less than 1" of ground clearance when measured at the skidplate. A dual sported BRP takes corners like a sportsbike.
