What size dirt bike is good for me im 5,10 250 pounds?

Looking for a trail bike not new to motorcycles but never rode a dirtbike


Answer
first off, I am 6'3" ~260 lbs and have been riding motorcycles for roughly 45 years, dirt mostly...

if you are looking for a less expensive trail bike, find a good used XR400 ('99-2004), 500 (82-85), 600 (mid 80s-mid 90s) that is in decent running shape.... don't worry so much about the normal wear parts like tires, chain, sprockets, brakes as those can all be upgraded and are readily available still. these bikes are bullet proof air cooled 4 stroke with all the latest (for their era) performance equipment with plenty of torque ... but they are very heavy (280-300 lbs). I owned probably 10 of these from '82 up thru the late '90s, they will not let you down and are great trail bike for a heavier rider.

other alternates would be a DRZ400 or KLX400 but might be a little more pricey (not much though).

others that are going to be a pretty good jump in price would be moving to a CRF450X or WR400 / 450 but these are newer models. also you might even look into the XR650 too.

then moving on up higher in price but well worth it are the KTM EXC (prior to 2007) models or the XC-W (2007 and later) models in either a 400 / 450cc or 520 / 525 / 530 but these all have the latest high performance aftermarket parts on the bike coming from the factory.

if you are looking for a good trails bike, stay away from the MX bikes as these were designed for high rpm track riding and will easily overheat at lower rpm on the trails, also have very small capacity oil and will be higher maintenance in the long run... this would be any of the bikes like CRF, YZF, KXF, RMZ, KTM SX... not to mention these are not designed for torque in pulling hills unless you have it rev'd up ...

if you want to go with a 2 stroke, something in the 250cc range like a CR, YZ, KX, RM and then merely play a little with sprocket gear ratios and the addition of a 9-14 oz flywheel weight to give you more rotational mass to increase the torque and make it not as peaky (tones the 2 stroke power band down)... also look at the KDX 200 /220 which is set up for enduro that already has the gearing & added weight from the factory (these are just a bit too short front to back for my height but alot of fun to ride).

another very good option is the CRF230 which is based on the XR line engine with an electric start but is limited in suspension & brake performance parts but it's a great little bike. I ride my daughters probably more than my KTM 525 EXC just due to it being a bit shorter seat height and makes it easier to get off and on when I am working cattle or running fence lines...

anyway, that should give you a pretty wide range of things to start looking for that would suite your size pretty well. find one that fits your price range and you will be set...

Is this bike too heavy for jumps? approx weight 350lbs bike plus 170 lbs rider , when I took a jump at 35km /p hour the nose end went down first hard landing for me , I know your suppose to land gradually back end to front , what can I do to this bike to lighten the weight or improve my jumping , besides speeding up and getting a smaller bike


Answer
It's too heavy, plus the suspension on the thing is pretty soft for it's weight. Only way to loose weight is to get rid of the headlight, battery, and electric starter.

It sounds like your suspension is really soft. I suggest you stiffen the compression and make the rebound faster. On most 4 strokes, the compression adjustment screw is on the top of each fork, and the rebound is on the bottom. It just takes a flat head screwdriver.
