185hrs GPX TSE 250R Engine Service (Pt.1)

[@arthurstudley50]

Thanks for doing this video,i found it very interesting, a few things i think you should have pointed out to inexperienced viewers, probably best for them to start the bolts by hand, be careful not to use too much silicone as it can come off inside the engine and especially on 4 strokes block oil ways, and we were always told to lift the barrel slightly then stuff rags around the conrod to avoid any potential broken rings etc falling into the crankcase, i hope you take this as intended as constructive criticism, looking forward to seeing more about the gpx

[@RobboRobinson]

Thanks Arthur no offence taken. This was intended as more of an update on how the bikes holding up as opposed to a tutorial but thanks for your interest and you are quite right in your precautionary approach. 👍

This thing has surprised me ..OK not the fastest bike on earth but my god its durable and strong. I'd never thought I'd say this but excellent bike.....I've sold the crf450r I'm done with dirt riding picking up a 2010 cbr1000rr fireblade today 16,000 miles absolutely immaculate full service history with honda 3 owners since new I can't wait 😀 👍

You’ll regret it street ricing sucks. I got a CBR600RR I’d trade for any dirtbike lol and I’ve got lots of em already. Fugh street bikes not nearly as fun as dirt.

Good Job, Bro❤

[@rphanukkah]

Hi Robbo, when you installed the piston rings where did you put the black ring? Thanks

[@RobboRobinson]

The rings are different thickness to each other so easy to work out.

[@claretbuck1882]

Awesome bud cheers 👍🏻

[@FZ1RIDER]

Hey, i have a 2019 tse gpx 250, i was wondering where did you get your piston kit from. I've looked on google but i cant find a top end rebuild kit.

[@RobboRobinson]

GPX Moto UK supplied mine. Have you looked on AliExpress loads of stuff on there just search, Hengjian .

[@crowncanopies9532]

Hi Robbo what 2 stroke oil do you use in the 250 GPX

[@RobboRobinson]

Motorex cross power 50.1

[@briansmale5457]

It's a bit hard to tell from the video, but the clutch basket looks small, more like the size of a 125 ?

[@RobboRobinson]

Yes it’s a little smaller than the 300 2 stroke but quite robust considering.

[@GeraldFronda-t4b]

Hello sir. Just planning to purchase GPX TSE 250, Can you really recommend GPX and its reliability? Thanks for sharing this video

[@RobboRobinson]

Hi there, my personal experience is with the 2 stroke bikes. TSE 250 & 300 models. Both are totally different machines in performance and weight. From a reliability point of view the 250 has proven to be a robust dependable machine. I ride it hard and always on the pipe. It’s a tame bike though compared to the 300. The 300 still has to prove longevity still I’m 18hrs thus far on this bike. However I am confident it will go the distance but engine maintenance like piston changes will be more frequent like every 60-70 hrs to get the most out of it unlike the 250 which did 185hrs because it’s tuned differently. Otherwise from a frame , suspension, wheels, brakes, electrical perspective I personally have no problems to complain about. There are a few things I don’t like on the bikes when they come stock hence I make subtle changes to make the bike meet my needs as a rider. Light switch , change a few fasteners to suit my tools , add protection , delete indicators -speedo for example. My question to you is, why the TSE 250 and what’s you preferred riding style , ability , age? Is this the right bike performance wise or do you really need a 300.

No gorpes la tapa para entrarla se puede romper el piñon de la bomba de lubricación o el del agua.

[@garywilliamscornwall]

How does it compare to other bikes in the market. I'd think 185 hours was really good for this sort of maintenance

[@RobboRobinson]

Clutch wise it’s on par with a KTM . Bearing in mind it’s not of the same performance as a an enduro bike it’s about right piston wise to normally go twice as long as say a TPi bike which would be 80hrs

[@Tpitill]

My 2019 300 tpi done 250 hours on the original piston was still putting out 178psi and the piston still looked good when i pulled it out ✌️

[@RobboRobinson]

@@Tpitill blimey you are lucky my 19 TPi needed a complete rebuild at 200hrs crank everything

[@Tpitill]

On my old 2019 it had piston at 250 hours size b vert x oil pump at 80 hours i sold it on 314 hours to a mate who know uses it for green laning still runs a dream and my current 2019 300 tpi has currently 108 hours only thing changed from new has been the tsp head and remap runs like a swiss watch

[@Robis_Grigoris]

It's a DT230 LANZA engine. it is a super reliable engine tho the clutch on it is pretty weak as the engine was intended for on road use. Also, the power valve isn't working properly on 90 percent of these bikes so they barely make 20hp

[@jasons44]

Is it a Honda clone engine?

[@RobboRobinson]

@@jasons44 It’s a Yamaha engine made by Loncin called MT250. You will find it on the Loncin website.

[@krazed0451]

Not the first of these I've seen with broken clutch fibre plates, not a great sign.

[@RobboRobinson]

I think it’s done pretty well considering some of the Sherco’s I’ve seen with broken plates at 30hrs.

[@krazed0451]

@@RobboRobinson Perhaps I'm not hard enough on my bikes...

[@Oouther1]

We bought a 2006 YZ250F new, broke plates in 8 out of 12 races and couldn't keep it on the track. Finally sold it and finished-up on a 2008 CRF250R, 86 hours with no troubles except valve replacement at 17 hours.

[@Africatwinrider1]

My £1470 2012 300XC all day long over these new bikes. Well used, well looked after, hasn't given me an ounce of trouble. New bikes are just too expensive, Chinese, Japanese, European, the lot!

[@TraveladvRajanSRai]

Usually more. Rebuild?
