[kg450x]

Hey guys/gals.
A neighbor bought an '07 150r/expert last week and he wants to know how to tame it a bit so he can ride trails/woods, etc... (no mx) with his boys who have a 50 and a 70 - both crfs. He's 175lbs. I spent several hours combing this forum looking for examples of doing so. Aside from going 1 tooth down on the front sprocket (don't recall who posted this potential solution but thank you), I have not read any other simple ideas (I don't think he wants to get into it to the extent that a heavier flywheel will require). It's a 100% stock bike. He says it's as quick as my 450x with the mods that I have done. I have yet to ride it but am looking forward to seeing what its got under the hood. So, is there anything that he can do to make the power more manageable?

Thanks in advance.

Going down one tooth on the front will make it even harder to handle, maybe up one.

The flywheel weight is the answer...

Pound for pound it is quite impressive. I somehow doubt faster than your 450 however it will loop out with a fat boy (230lbs) riding it so be careful. The flywheel weight is the easiest thing to do and he needs a 9oz. We had the carb re-jetted on my son's and he seems to feel it made it easier to ride and definitely easier to start based on the fact it is now getting fuel and you don't have to stay in the throttle. He could also look in to a torque style exhaust. These are some of the things I have researched for our 08 R/B. I hope this helps.

We tried the one tooth smaller front sprocket for trail riding. Its only benefit to me was in the really really tight stuff I could stay off the clutch a little more. I will admit that it would have been more comfortable to ride my bike when I got it with a smaller sprocket. My riding got better very quickly because I had to learn to keep up with the bike. Front sprockets are cheap at about $10 to experiment with. I run a 15/51 on my bike now, but I am woods racing. ~ has not steered me wrong and the flywheel weight is really the way to go. Really

Thank you all very much for the replies.
It looks as if he's going to bail on the R and get an F. Trying to talk him into a 230f but it's a little tall for him. I'd better get over there before he sells it to see what it's got

ehhhh bad idea. the f is so slow and has horrible suspension even for trails and is much heavier then the 150r . 150r has 2x the hp i think 23hp 150r and like 11-14 for the 150f

The saga continues...
He came home with a 230f tonight. I was glad to see that vs. the 150f. Apparently it has 12 hours on it. It's a 2006. Looks great throughout aside from some chain neglect. Seems every bike that I see that was formerly owned by a kid has a bone dry chain in the least. Maybe it's just me (I am 39) but isn't caring for a bike half the fun?? I gave him a spare can of my Maxima lube so hopefully it gets a few good coats soon 'cause it's noisy when riding it.
Runs great although it feels like it's a great candidate for some mods. Little to no bottom end power. Seems to get going when it gets wound up and pulls fairly well higher up in the rpms. The suspension feels like a '70 Lincoln! Reminds me of my '90 XR250R. I will have to do the brew spill test on it sometime it's so smooth! The front edge of the rear tire knobbies are worn just slightly. My question is were the original tires Pirellis? The front looks too new so I am wondering if it's had new tires put on it recently. Guess that would dismiss the 12hr claim. I told him to change the oil asap.
Anyhow, didn't get to ride the 150r/expert. He has a souped up VTX1800 though! Spring is right around the corner!!!!
Lots of red on my street
I will have to comb the 230f board looking for some ways to spend him money on mods now! Woo-hoo!
You guys take care.
