Hi !
I have met recently a GP rider, a close friend to a good friend, who is missing maybe 2 or 3 seconds a lap to really be on the map and crack the top 15 regularly.
Not talking about the rider (he is fit, trained and coached), we also all know it is a motorsports, so that made me wonder what mods could help to make a little step. The current bike has already good engine mods + ignition, semi or factory suspensions, clamps, wheels, in other words it is really far to be the fastest bike (like 25th at the start...) but it is still a fast one compared to the shop floor.
So, with all the knowledge some people here have, would you know or would you please recommend certain parts or mods ?
1. I saw a thread recently about a RMZ owner that was super happy on his new Ride Engineering brake caliper. I checked but it is not available for KTM/Husky, maybe the stock version is already great, or is it for another reason.
2. I think there are "factory" calipers in the ktm/husky catalog. Has anyone tested it ? (and how much does it cost?)
3. Would you recommend something to improve the braking on this bike (pads, line) ?
4. The seat on the husky looks light, do you know how much weight would be shaved with a motoseat (or acerbis) complete seat ?
5. Has anyone tried the Zeta adjustable lowering link ?
6. Husky/KTM are super light, would you know what kind of weight could be shaved for let us say $1000 ?
7. I didn't ask if he had a hinson/rekluse, would it make a big difference ?
8. I didn't ask if he had internal treatments, would it make a big difference ? (and for what cost?)
9. Any ideas are welcome !
Thanks !

If you consider yourself a "fast rider" already you should be able to answer these questions yourself
The Shop
I also forgot to talk about offsets that could help a relatively not too tall rider (about 1.7, 1.75m).
Last but not least, I really know that some modifications, combined, can gain that much ; and you are right about the suspensions. Here he told me that he has something pretty good, it is also why I am searching a bit in the braking/engine/weight department.
I think I will also send a pm to Derek Harris to see how much HP/torque he can get, to pass the info (and the quotation), to compare with his current dyno numbers (the issue here to compare is the noise & fuel different regulations).
I would look at them questions and that will help find the problem.
Tips
1 Have the same setup for the race bike and practice bike. The race bike motor and practice bike motor can be different that's perfectly fine.
2 Check the subframes on the bike because we had one crack and had no clue for probably 4 rounds of outdoors. I'm not sure if they fixed it on 19 Models.
3 Don't buy TI bolts
4 OEM Clutches are really good you don't need aftermarket IMO
5 Don't buy Brake calipers or Brake master cylinder waste of money OEM are all ready good.
Mods
1 High Compression Piston
2 After market pipe
3 Front Forks Cone Valve or KYB are diffidently worth it
4 Stock shock with a bladder kit is really good or a Trax shock both work great
5 Bar setup helps a lot
6 If you have extra money you could test linkage and knuckle on the bike I would try and make the bike longer if he's racing GP. My brother ran a stock linkage and knuckle.
That's about it for mods on the bike. You don't need to spend a crazy amount of money on a motor. My brother raced a 2019 KTM 250SXF at the last round of MXGP in Italy on a stock motor and got 18th in time practice on a bike with just a pipe, Cone Valve forks and Trax shock.
Hope this helps you guys save some money because racing is crazy expensive. If you have any questions on parts just send me a PM.
i think there is a lot to be gained with mapping and traction control setup to your mods and fuel.
i heard (not positive) the 2017 dixon bikes dynoed at 52 hp at the rear wheel with a slick tire when they came to race in Leon Mexico.
The bike is competitive vs the factory equipment - as they have had multiple fastest laps, top qualifier etc against all colors and teams.
Do I think what Im selling is better than the factory stuff?
Hell no.
The top team level stuff is well over 16000 rpm team depending with practically no budget limitations.
Are we close enough to do well?
Yes
So my suggestion is mostly hard work with chassis and suspension. I can plug in 5 hp with someone - and see less than .5 second improvement - it's the nature of the beast. And in no world is a decent mod engine more than 5 hp off the best one out there. People can't seem to realize this - if you are 10 percent off (a huge amount) it's 5hp.
Where you are way off is RPM and what that brings with it...something you truly wont want to dabble down budget wise.
I can get a small set up improvement on suspension - and I mean small - and see 2 seconds a lap
Just properly testing sag, fork height, clickers, round and round and round - does wonders.
We don't have access to the really trick stuff top teams do - and IMHO that's the majority of the difference in bike.
The top 5 in GPs could ride stock engines and still ALL top 10 on their factory chassis.
lastly - make sure you run the lightest of parts in the wheels, tubes, tires, chain, sprocket. Most privateers end up with HEAVIER parts - which negates a lot of hard work they put into their motor....
I would invest NUMBER 1 into data logging. Seeing what rpm he is at, what throttle position, what gear, and track position will help educate the team and rider as to where to improve the bike.
Suspension is hard to data log and make headway on - but it can be useful when a rider is a poor test rider.
On the Husky, is also suggest a Vortex EcU with better mapping.
I’d put money on it that with those changes you can cut time all day long.
Hold it wide open longer brake later carry your speed through the corners.
And a big set helps
Hope that makes sense.
I think your boy CAN do it, but it won’t be as simple as modding the bike or working out more. It’s going to be .02% advantages in 6 different areas...
Used by Fact yamaha and jgr (yeah yeah, top results i know)
It will do track data - PLUS bike telemetry....
I THINK (but don't know) litpro is doing similar for KTM.
