ltr 450 hybrid goin start need help

[walsh302]

Hey I am looking to start a hybrid build I about to buu a full race ready ltr and take the motor out n pit a dirtbike motot in any help on wat motor n wat should I do for an exhaust n all

[rustyATV]

I was actually just looking into LTR's to see if a TRX250R motor would fit.

[walsh302]

The only motor I heard of was the ktm 525 but I want 450 good luck I do not think it will fit

[rustyATV]

Height-wise, 250R should be an easy fit; it's smaller than most four strokes 450cc and over. Only issue may be running the pipe; need sufficient space between the upper and lower a-arm mounts and below the radiator

[walsh302]

Well if u ever do it send me some pic

I would either stick with a suzuki powerplant or go with a efi crf one like WRC is doing

[headache]

i'd go with a 05-07 rm250 motor. would be awesome!

[walsh302]

Mx ell where can I find thiese motor

[mx Eli]

u can buy a crf motor off service honda i think but iw ould prolly be cheaper to buy a used bike ( i found a 2010 efi crf for 5000) take the motor and everything u need and part out the rest.

and if u go with a non efi crf u can get those things reallllly cheap

If interested I have a nice KTM 450SX dirtbike motor as well as a 03 crf450 motor for reasonable prices.

RMZ450

I guy I know put a rmz 450 09 in a ltr, It is a lot of work, and you need to make a lot of changes he said. But it is definately possible.

rotax 257cc 2-stroke.

Let me understand this you have an LTR450(frame/motor) you wont to change motors to something else? is this right?

[walsh302]

I would sell ltr motor and buy a diff nmotor to put in

[diangelo#67]

believe it or not the ltr motor makes more power then the rmz if you change to a carb an have the motor built, that ltr motor would rape a rmz motor with the same mods.

[diangelo#67]

the only advantage of the dirtbike motor is loosing the injection system weight the ltr's injection system an frame are the heaviest of most machines so the sickamount of power they are making is only averaging out with the sheer weight of the bike

[walsh302]

yeah i think i willl do wat u just said will save time n money thanks

I'm in the process of gettng a walsh chassis together myself. for the weight an handling..not the power of course it feels powerful but its the eight that makes it that way
