I’ll have the option to buy a used 2019 ktm 250sxf in a few months. I have a buddy who’s a B rider (mid lack national b rider) and has a deal with the dealership.
I’ll be able to pick up the bike he returns (2019 250) for like 3k off original the price. So my question to you guys, the engine will be left untouched. So At 40 hours, should I look into swapping out the crank and top end in the next 10 hours of ride time? (Bike will have 50 hours at this point)
And probably get the suspension overhauled to get the bike feeling like new again some time after engine rebuild. How much should I expect to pay for that?
I’m thinking a crank, around 600-700 or so, and top end would be around 400. Or am I way off on the prices? I have another friend who can rebuild engines and works on ktms regularly so labor cost won’t be as high as usual. Opinions? Would I be better off buying new? How long do the new 250fs last this will be my first 4 stroke

Bottom end should be ok for 75-100 hours easy.
But in the end you need to add up all the costs, suspension service/valving, chain/sprockets, tires, brake pads?
The Shop
I swap the top end (Piston, top gasket kit, cam chain) every 50 hours (it is a common rule) and of course i could do more but then you take a risk and you might worn out the engine in a wrong way.
Is your friend a rever ? If so, don't wait over the 50 hours mark.
Other than that the new katoom are reliable, it is a great bike good choice,
PS: About the suspension, if you have the money, go with the spring inserts (KYB / Dal Soggio / Ohlins). Way better than the air fork (only major downside of this bike).
so cranks generally last around 80-100 hours playing it safe? Cool. How much can i expect a fresh top end to cost? Oem parts. Valve train and piston/timing chain should be checked and maintenances should prevent blowing engine?
Either find a couple of grand and buy a new KTM or buy a brand new leftover YZF for the same amount as your 50 hour old KTM.
Weight is around 175 ish with gear. Doesn’t ride the bike revved out, but occasionally is on the limiter before landing depending on section.. bike is well
Maintained, new oil filters is replaced as per
Manual says, oil changes every few rides... if he were to race LL he’d be liked 25-30th In B class so he’s not blistering fast. I think his best finish on this bike was an 18th in college boy at This years party Ponca.
So when I buy this bike, 40 hours on it, I would probably want to rebuild bottom
And top (with oem parts) and it would
Be fresh? Or is there a lot of other things I’d probably want to go over?
I’m not sure how much Cheaper the bike will be once Mumm post it back up for sale. I was just guessing 3k off msrp?
Base price for 2019 250sxf is 8,999
So let’s say I can pick it up for 6k. Would it be worth it even if I have to throw in a new crank and top end?
Pit Row
The $3k savings might not really be worth it. I’m sure you can get a 19 either for close to that or maybe another brand?
The used game with 40 hours is tough, really depends on how well the previous own did with mantaince. Maybe try and get him to $5k, then you are looking at an upside even after engine rebuild.
