1) your physical size-5'8 140 pounds
2) How physical / aggressive are you ? fairly aggressive
3) what do you plan to ride- mostly hillclimbs and trails and a little bit of tracks
4) Do you have any riding experience? some 1-2 years on a dirtbike so I know the basics.
5) Do you think you will race ? no
6) Are you mechanically inclined and will you be doing your own bike work? yes
7) Do YOU have a preferance to a brand/ motor choice (2 or 4 stroke)? would like a 2 stroke but a 4 stroke would be fine
8) Do you have a dealer close by your home that you might use and what brand(s) does he carry? n/a
9) How much ($) do you plan to spend on a bike? 700=2000, used bike most likely
10) Do you live in California? no
11) Your age? 15
I currently have a 99 kx125 that i took hill climbing which turned out to be too big for me, i ended up riding my friends crf150f,

i was wondering whether a 85 2 stroke would be bad at climbing hills, and if i should go with a bigger 4 stroke offroad bike, such as a 150 or 230.

seat height is a big factor here, the lower the better.

dirtbike2244, the bike you currently have has great potetal to be a wounderful hill climber in comparison to a 85. First, you buy a lowering link http://www.koubalink.com/KX125-250install.html
then cut down your seat foam or buy a low seat foam mabe for the bike http://www.seatcoversplus.biz/KawasakiBikes.htm (down at the bottom)
last you buy a flywheel weight to inchrease the rotating mass of the engine to creat a better less stalling slow speed bike http://www.steahlyoffroad.com/weightsdet.php?s_partnum=620_ ( get the 9oz one)
Also, a FMF Fatty pipe helps alot.

You can also have the suspension lowered by a pro for about $250-400.

dirtbike2244, i think it is worth it seeings how you would have a much faster, funner, and cheaper machine incomparisson to a new or newer 150 or 230.

The differences between the 230 and 150 are:
230:Engine Type air-cooled single-cylinder four-stroke
Displacement 223cc
Bore & Stroke 65.5mm x 66.2mm
Compression Ratio 9:1
Valve Train SOHC; two-valve
Fuel Delivery Single 26mm piston-valve
Transmission Six-speed
Final Drive #520 O-ring-sealed chain; 13T/50T
Front Suspension 37mm leading-axle Showa fork; 241mm travel
Rear Suspension Pro-Link Showa single shock with spring preload adjustability; 229mm travel
Tires 80/100-21 front; 100/100-18 rear
Brakes Front Disc; Rear Drum
Ground Clearance N/A
Seat Height 866mm (34.1 in.)
Wheelbase 1374mm (54.1 in.)
Dry Weight 108 kg. (238 lb.)
Fuel Capacity 8.3 L (1.8 Imp. gallons)
Colour N/A

150:Engine Type air-cooled single-cylinder four-stroke
Displacement 149cc
Bore & Stroke 57.3mm x 57.8mm
Compression Ratio 9.1
Valve Train SOHC; two-valve
Fuel Delivery Single 24mm piston-valve
Transmission Five-speed
Final Drive #520 O-ring-sealed chain; 14T/50T
Front Suspension 35mm leading-axle Showa fork; 230mm travel
Rear Suspension Pro-Link Showa single shock; 223mm travel
Tires 70/100-19 front; 90/100-16 rear
Brakes Front Disc; Rear Drum
Ground Clearance N/A
Seat Height 825mm (32.4 in.)
Wheelbase 1327mm (52.2 in.)
Dry Weight 101kg (223 pounds)
Fuel Capacity 8.3 L (1.8 Imp. gallons)
Colour N/A

Now i fine the 230 to be a bit heavie for its power where as the 150 is more nimble and the weight is more centrial. The power differnce is 16-17HP for the 230 stock and 12-13HP for the 150 stock. With some lots of performance goodies the 230 can make 23-24HP and the 150 18-19HP. I still think your current bike is alot better having about 30HP stock.

i thought the 230 seemed pretty heavy, ive got a 4 tooth larger than normal rear sprocket thinking that it would increase the lowend, is that helping any? And do you know if there are is anything you can do to increase the low end? thanks for the help

the kx 125 ive ridden wasnt very powerful considering i could ride a wheelie on my cr80 and i couldnt get my front tire off with a kx 125. But ive seen 8 year olds riding cr250's around at some tracks.

if you are looking at the 150f look at the 150r.

it is alot better in weight to power ratio. the 230 i find to be too heavy and the 150 is crazy heavy. a crf250r is about the same as it.

the 150R though is a great bike. lots of lowend. lots of power.

only problem with the 150r's are that they are out of my price range, are the kdx 200's and 220's pretty good for hill climbing?

i personally would just stick with the one you have and lower it if seat hight is that important to you. your going to spend alot more money fixing up a 150r to even get in the same area code of power that youd have with yur 125. yes you are going to have to put some money in the 125 but it wont be near as much if you bought a 150r and put a bunch of aftermarket goods on it.

how tall are you? i'm 5'7 and have a cr125 and havnt done any lowering mods. u should just chop the seat foam, lower the pre-load and slide the forks up in the clamps if its too tall.

Race_Bennett, thats horrible advice the has hardly any relivance.

crkid33, FunkyD, that is what i think would be best. He just needs some mods done to it to warrent his style of ridding.

dirtbike2244, the KDX200 or 220 are fairly good hillclimbers but lack the snap your 125 has but that might not be a bad thing. The power is really smooth like a 4 stroke.

yea thats the main problem im having now isnt so much the seat height but clutch control, for some reason on my bike the clutch is very very draggy. Ive checked the basket and nothing seems to be wrong. It also has a tendency to die if your going through some tight technical trails and you dont keep the revs up, but the clutch doesnt hold so i ended up going too fast and crashing through a rut that was 3 feet deep.
