Subframe cutting....

[BlackTrx440ex]

iam having my subframe cut 1/2" like the people do to the kawi's i know a few people that did it a few pro's in the area and they love it!!! i got a good company that does them if you want yours done ill get pics appon request

[pro-rider46]

whats the point

[440ex kid]

whats the point



I dunno, but lets see some pics.

[BlackTrx440ex]

how can you possibly say wats the point? lower seat height = lower center of gravity= better handling, its like saying why do people cut the subframes on the kawasaki's?

[TAZ450r]

i did just drill a new hole in the lower subframe mount, but dosen't know if it works yet:)

[BlackTrx440ex]

5 people in this area just did it and they said they wish they did it 2 years ago

[DEERCHOOPER]

i dont read the kawie section but have a few questions.

when you say cut it 1/2", are you just cutting off 1/2" off of the lower tubes to lower the rear of the sub frame?

if not, what are you cutting then?

[BlackTrx440ex]

yes iam sorry i wasnt clear about that its cutting the 2 lower mounts 1/2" back and it lowers your seat height....

[rollie]

iwould guess it depends what rear end you have too, i wouldnt want my superlink sitting any lower than it already does, already had to lift the airbox, haha

[TJ Bradley]

I 2nd that rollie, I would like to see if it would clear tho.

[TJ Bradley]

What kind of rear end set up are you running BlackTrx440 ? i would like to see pics of this when you get it done. I want to see if my Rear setup would work with out running into any travel problems. Im running a JB Swinger with LT Axis shocks, And a GT thunder MX link. And my air box is already lifted. ???? If it would clear id def do it. Post some pics please.

[HondaRaceReady]

Are there any disadvantages? Like does it make it uncomfortable to sit upright? Does it lower the middle of the seat or the back? Does the seat still fit on good or do you have to bend it a little?

i did cut just a litle of the subframe and made new hole in the lower mount! lowered it about 2 inches in the back of the subframe. the seat dosn't mount perfect, and it feels like the pegs are realy hi, but i think it's nice!!

[BlackTrx440ex]

my quads torn down but my buddies has stadium rear suspension gt thunder link on an 06 swingarm

[S.A.J]

we realy need to get some pics of this up here cause if its all that and more i wana do it to mine while its still in pieces

[BlackTrx440ex]

that guy just posted some pics... i wont have mine together till towards the end of the month its all going for pc the end of this week

[cmaxx]

would it be good for XC racing?

[blacknblue#2]

Im 6'3 with some fairly long legs. I dont think this would be a good idea for me if it makes the pegs seem higher

[HoleshotR15]

I like the touch that the camo tires add there! lol

[SHIFTx450]

Hmm... Interesting.. Who else has done this?? More pics?? I wanna see just how goofy the seat fits afterward... And how do other people like it??? Does it make it feel like the old 250r?

[hotrodbelair]

im waiting till i get my shocks then im gonna try this im still debating wether i should cut it or do like that guy did in the picture and just drill a new hole in the mount.
but im gonna wait till the quad is sittin on the ground on its own before i start messin with that. another thing i was wondering is if your rear master cylinder is affected by this like should the mount be cut off and moved up or can you just adjust the pedal to work with it.

[TAZ450r]

be cut off and moved up or can you just adjust the pedal to work with it.
i had to cut it! and i also lifted the airbox, just in case!

im thinking of make a new set of lowerd pegs to!
but if i realize that it dosn't work whit the frame lowered i can just put it back in the stock mounting hole, and it's fine again!

so you cut the subframe and drilled a new hole on the mount? how much did you cut out of the subframe to lower it that much. i think i would just want to lower it a inch for now.

[BlackTrx440ex]

i wouldnt lower your footpeg mounts they will hit the ground if they get any lower.... say you bottom out and your footpegs hit the ground your done... my quad should be up and going by the end of the week ill get pics!!!!!!!

[warr72]

If your a shorter rider this sounds good but I'm 6'1" and I think it would hinder my abilities more than help.

[BlackTrx440ex]

1 of the kids is over 6' i believe mike pillote and he loves it

[TAZ450r]

as long as the peg's are higher than the frame it shouldnt be any problem! i like to build my own part's and some time they work and sometimes the dosn't!

http://i40.tinypic.com/25styf5.jpg

i did cut at the red line, as close to th hole i could! and than i just drild the hole in the mount as close to the frame as possible!

[wayfastwhitey69]

will the exhaust hit the brake tho?

[chillinsk8err]

does it effect how everything lines up

[wayfastwhitey69]

i just did it to mine and nothing will line up at all

[Pappy]

If I am not mistaken, the end of teh subframe you are cutting is double walled for strength so the aluminum doesnt fatigue and crack. If you drill outside that area or cut it off, you are going to be having some issues.

[RideRaceLive93]

well if you did it like taz did it it shouldnt be to much of a reliability risk if you weld a new top to what you cut off im seriuoly considering this not as i do xc racing and a low center of gravity is needed

[RideRaceLive93]

and as for the rear caliper hitting the exhuast you could probably raise the exhaust but i have and hmf with is smaller in diameter so it doesnt hang down nearly as much and you could get a houser airbox lifter kit and your on your way rippin through turns

lol

[BlackTrx440ex]

let me see if i can get my friend to post up some pics i dont know if he took any or not when he had it together but ill find out i know he loves it

[RideRaceLive93]

you could prob get away with just grinding the top a little bit and youll still have most of the strenght with out having to weld a peice back in

does anyone els have better pics on how they did it and after pics of how things mount up?

[quad2xtreme]

If you have $700, Walsh makes a chromoly subframe that is adjustable.

I know some of you do...I've seen your quads. :p

I think alot of us would not mind spending the 700$ on a walsh one, but they are going to be 3 times the weight of the stock one. Thats the reason why i dont want one.

[Live2Ride300]

Hello, we've done quite a few here at the shop. I did my personal bike as well. It feels almost like a aftermarket framed 250R. I also lowered my gas tank mounts on my personal bike as well.

Pappy, you have to re-slug the tubing. If done correctly it just as strong as factory, we haven't ran into problems during testing so far. As far as clearnce goes, everything clears except the chain will "love tap" the airbox if using the stock setup. To mount you must modify the rear master cylinder stud. Also, if running footguards, the mounts will have to be modified.

The modification deffinately makes a big difference, it feels like a new bike. Every aspect of handling is alot better.

Have fun guys,

[Live2Ride300]

Btw, i'll post up some pictures soon. I actually just took my bike apart to do swingarm bearings, and a few things in the motor. As soon as she is back together, I'll snap pictures for you guys.

[hotrodbelair]

how much did you cut out of the subframe.

[Live2Ride300]

We move the lower mounting holes a 1/2" higher.

Theres a aluminum insert that goes in the tubing right where it mounts up when you move your mounting hole up on the subframe you aint goin into that insert, just goin through hollow tubing that aint very think. after time it will oval out the hole and possibly break.

[Bwild]

Could you use washers inside the tubing and torque the bolt for a pinch grip as well?
