GPX TSE 250R 30 Hour Review

As promised a 30 hour review of the GPX TSE250R. How is it holding up? It has to be said I have been trying to kill this bike riding it hard all the time but it's not giving in just yet. An enduro bike with a trail bike engine I think we have a long way to go before we have to breakout the tool box.
If you are just getting to know what is going on with this bike I would say watch the video below first.

My apologies if you already covered this, as you may know this bike has become really popular in Brazil because of the prohibitive pricing on the mainstream brands, so people are really trying hard to get better performance out of this engine. One of the very first mods we do in order to get better bottom end power is to shave the head to bring compression up, usually shave around 0.6mm to 0.8mm. Another thing is we mod the pickup coil bracket in order to get about 2-2.5 degrees of timing advance, this also helps get a bit better bottom end power without any downsides, the stock timing is really on the mild side of things. Even after this mods it still is quite a tame bike, but it really does improve it's traits for more technical riding. We also have a brazilian made programable power valve module, the stock module makes the power valve open very late in the rpm's, this brazilian module helps the engine to wake up sooner. Cheers and good luck with the bike!

I'm very happy with this bike here in Brazil!!!! Made some changes in the carb head and a v- force valve it's very good now!!!!

[@АндрейАндреевич-д5г]

hi, what exactly did they do with the carburetor and valve? thanks))

[@tonyfry5455]

Really liking the regular, unbiased updates from real world experience. The carb swop is interesting, so will look forward to that vid. Be nice for you to do a 250 Vs 300 post when that gets here...🤞

Great review! I own one of these bikes and have really enjoyed it, no problems so-far. Looking forward to your future reviews and mods, Thanks!

[@RobboRobinson]

It would be nice to see some content on the tube Dave about your bike. Thanks for checking in.

[@ajr.1272]

I just saw in the video that your Gpx comes stock with a 12 tooth sprocket, here we've been getting them with a 11 tooth stock since 2021, and it was one of the main mods for the older models.

[@ajr.1272]

And just to point out, we still have a very, very durable engine even after these mods, people in Brazil are not really into preventative maintenance, they usually run untill it breaks. And even then, we have a lot of bikes with many, many hours on the clock.

[@RobboRobinson]

Hi bud, I have no doubts on reliability of the bike. In the last day I have got the XTNG carb really dialled in now and the bottom end is much improved as well as all round performance. Its a great bike for your buck. I have been told about the other performance mods but to be honest its a second bike for training and the odd hare scramble so I am really happy with the way it runs.

[@ajr.1272]

[@RobboRobinson]

100hrs so far now and no mechanical failures. The bikes had a hard life so far and still shows no sign of giving in. I’ll be doing a 100hr review in the next couple of weeks when I’m not weigh layed with home stuff. The 250 is not a a full enduro engine more trail based so lacks on bottom end grunt. Power is there but more mid to top end. Asking some one like Billy or Graham to review it would be a waste of time. It would not be anywhere near their expectations from a performance point of view. More aimed at the trail rider, fun rider and occasional racer and those people who just want a cheap low maintenance bike. I reckon 200hrs before this will see a piston change or a clutch. Thanks for commenting bud and look out for the next review in a couple of weeks. 👍🏻

[@Superdisco199]

The old WR200R went pretty well.. I wonder if maybe it holds some secrets to getting more performance out of the GPX

[@RobboRobinson]

It may do but that may shorten the engine life of the GPX. I’d rather keep the engine tune stock for longevity. It’s still a ripper if you can ride if you know what I mean. 👍🏻

[@firecrackerlover4]

same engine as the wr200

[@jedidan045]

Greetings from Texas, USA!...really enjoying your channel and real world reviews and upgrades...have you ever ridden a Yamaha WR200 or Kawasaki KDX200?...if so, how would those bikes' performance and suspension compare to the GPX? Cheers!

[@RobboRobinson]

Greetings and thanks for checking in. I’ve never ridden a WR200 or a KDX 200. The suspension on the GPX is good and I would say on par with a KTM WP out of the box from a feel point of view. Actual build quality is good but I’ve yet to have the forks and shock serviced so we will see very soon what they are like to work on. From what people tell me the power delivery is very similar to a KDX 220. I’ve been riding today all good 😊

[@jedidan045]

That's awesome, thanks for the input...are you planning to change spring rates when you service the suspension or leave them stock?

[@RobboRobinson]

@@jedidan045 I think I'll leave it all stock it seems to be working well. Besides I don't want to spend anymore money on it. I'm trying to keep the costs to a minimum on this bike where I can. All I want to do now is put gas in it and ride.

[@painsrides]

I had trouble with my GPX, in fact I consider it a complete waste of $5k... It came out of the crate broken(blown rear shock, stripped exhaust bolts and a bad ECU) after more than a month of working the running issues out, I finally got it ridable. It did okay for most of the summer then somewhere around 40-50 hours the bike started to go to shit... from then on it was a nightmare and caused me to miss most of the fall riding season. Add to problems low quality fasteners and electricals which made the bike a complete pain in the ass to work on. Getting parts to work and fit these bikes is no picnic either.... I would have been much better off to have spent the money up front to get the known quality of an Austrian or Japanese machine.

[@RobboRobinson]

I see you had the FSE250R 2019 era bike probably built on a Friday. I know there were some issues with that era model. What can I say if you have seen my journey from the start with GPX2 stroke you will know I've sorted a few build quality areas of weakness out. But I've just ripped another 90 mins this morning and had a blast. I've seen people have big issues with the other bike like KTM and Sherco both high end bikes and sell them only a few months down the line as they are fed up with breakdowns. As soon as this fails people will know.

[@painsrides]

@@RobboRobinson Sorry but I don't agree... GPX's in any modle year are cheap copies and not close to the level of quality of the brand name bikes nor do they have a level of support when issues arise... You get what you pay for in this world, buy cheap you get cheap.

[@coltonowens2742]

@@painsrides As much as I agree that GPX falls short, "You get what you pay for" is an outdated way of thinking, and not remotely true. Price to performance is a better way to look at things.

[@painsrides]

@@coltonowens2742 I've never had issue with the GPX's performance, my FSE did fine and I enjoyed riding it. But the bike simply did not have the quality to stand up to hard use.. For the cost of a GPX you do get a decent frame and engine...but its completely wrapped in Chinese junk. Plastics, hardware, wiring, electrics, fasteners, efi\carb and suspension all cheap copies.

[@carlatamanczyk3891]

You are speaking the actual truth about Chinese knockoffs that too many others won't admit.

[@stoplogicmotorsports]

I'm really stuck at getting the 250 versus the new 300 coming out. I've ridden KTM 300 and I like the power but I just never felt comfortable on it. My last 2-stroke was an RM 125 and I've raced many kdx200 and KTM 200s. I currently ride a wr250r and can use that for tight Hard Enduro does the tse250r fit that point well enough or would you feel as if the 300 kind of a necessity for that?

[@RobboRobinson]

It depends on how hard or technically challenging the terrain you like to ride. Personally I still need a 300 for the harder stuff like Sea2Sky or Romaniacs where I’m going later in the year. The 300 is very forgiving if you get a wrong gear and can pull you through stuff with a slip of the clutch. At the moment I’ve got the TSE fully dialled in now with the XTNG carb in the last day or so. The bike has been transformed to another level from where it was. The bottom end is now stronger but not like a KTM 250 by any mean. Let’s not forget this is a 224cc and tuned for reliability. For flowing single track , woods and some technical stuff it’s pretty good but more aimed at the leisure side of dirt riding as opposed to racing but there’s nothing to stop it being raced. If I was going to have one bike it would be the 300 all day long. The TSE 250 for me has filled a space as I’ve sold an older 250 EXC. I needed something that was modern and would not break the bank. It’s done that very well so far and after riding it today I could not be happier with it. However I know it’s limitations and I still have a 300 TPi sat next to it if I need it. You need to really look at what you want from the bike if your choice. The price point is the big attraction with GPX which is good but choose the right bike for your needs. If you still race I’d say 300. I have a 300 GPX on order my 250TSE will be a long term fitness bike.

[@stoplogicmotorsports]

@@RobboRobinson I plan to race more with the GPX being my main bike and my modded WR250R taking role as back up. I honestly do not ride stuff like romaniacs the Rocky Ridge Stuff (video where I screwed up my WR400F) is about as hard as the racing I do gets. I am way older and out of shape than I used to be so a 23 minute lap on an 8 mile track is not in the cards. The stuff white hollywood rides is about as hard core as I get and to be honest I prefer a track with flow where I can stretch a bikes legs out a bit. I guess since my WR250R fills the niche of kind of a lazier dual sport a 300 would probably be a better buy for me. Sadly until I get the permanent house and a garage settled a second bike will likely wait until august. Thanks for the insight. Now for my big question guinea pig the PDS or stick with linkage. That however is a question I think I got on lock.

[@RobboRobinson]

@@stoplogicmotorsports I can take either but sway towards PDS for less maintenance. My 300 TPi is lowered in the rear shock and that gives it the edge I need in the way the bike handles at speed.

Mileage?

[@RobboRobinson]

Now at 200hrs no idea on mileage but a lot.

[@pat.125enduro4]

how's the engine holding up?

[@RobboRobinson]

Ringing its neck everywhere and it comes back for more.

[@sidecarbod1441]

I'm not sure that you can calculate the cylinder PSI by using the 'corrected' compression ratio, I reckon you have multiplied 6.5 by 14.7 to come up with a value just under 100 PSI. The thing is that even though the exhaust port is open during some of the compression stroke the fresh charge will still start to compress. The 180 PSI value for your KTM was probably an actual measurement taken from a bike, if you divide 180 by 14.7 you end up with a 'compression ratio of 12,24:1 and there is no way that the 'corrected CR is that high! In fact the geometric or uncorrected compression ratio is likely to be around this figure. KTM specified 12.8:1 on their older bikes but I think this is for the SX models, I measured the CR on my 300 EXC using a burette and maths!, it turned out to be around 11.2:1

[@RobboRobinson]

May be i'll do a compression test but yes you are correct in the way I calculated the figure I gave.

[@sidecarbod1441]

@@RobboRobinson I'm sure that the CR is a bit lower on this bike compared to competition bikes, the porting will probably be a bit more mild too, on the flip side I bet the piston will last a lot longer!
