jarrod Posted January 22, 2007 Report Share Posted January 22, 2007 Could someone please tell me the differences between the jtx250 and the txt250? Has anybody owned a jtx250? if so what are they like? Quote Link to comment Share on other sites More sharing options...
coxy Posted January 22, 2007 Report Share Posted January 22, 2007 the txt is a newer model than the jtx so will probably be lighter and have better specification and slightly more power, i think that the jtx has a different engine to the txt but not too sure Quote Link to comment Share on other sites More sharing options...
ridgrunr Posted January 22, 2007 Report Share Posted January 22, 2007 (edited) If I remember right, the JT models (JTR and JTX) were developed for GAS GAS by Jordi Tarres, hence the JT nomenclature. I think that started in about 1993. In 1998 Tarres moved on and the models became TXT. The main difference is that the JTX (and JTR models before them) had plastic fuel tanks. When the TXT came out in 98 it sported a new frame and an Aluminum fuel tank and new black anodized front forks. They were gold before that. The engines are very similar from the 91 with mostly minor changes but they got better as they refined the design. They went from 250 through 1996 to 270 through 1999 and 280 in 2000. They changed the frames again in 2000 when they got rid of the steel rear sub frame, and in 2001 GG changed the front fork. In 2002 they went to the PRO, however the TXT 280 was still offered for a couple of years. Prior to the PRO, The TXT models were the best of the bunch. I think the 1999-2001 TXT321 may be one of the best Trials bikes ever built. You can see how the bikes changed in looks here by clicking on the photos of the bikes on my web page here: http://www.geocities.com/utahtrials Hope this helps.

scorpa3 Posted January 23, 2007 Report Share Posted January 23, 2007 I have a feeling the 250 JTX was 238cc, the TXT was 249cc. IS that correct? Quote Link to comment Share on other sites More sharing options...
ridgrunr Posted January 23, 2007 Report Share Posted January 23, 2007 Yup the GG's were 236 cc through 1995. In 1996 they went up to 256 cc and they started calling them 270 in 1997 even though they were only 256. 249 cc is what Fantic used in their 250's Quote Link to comment Share on other sites More sharing options...
gii Posted January 26, 2007 Report Share Posted January 26, 2007 1997 JTX was a good bike. Engine design had pretty well stabilised by then, prior to that there was a fair amount of change, some things were tried and retained eg. hydraulic clutch, direct crankcase induction, some were tried and dropped eg. crankcases water cooled (heated?) Every year the frames were modified to be lighter (went a bit too far in 98 if memory serves) and engines developed wider torque bands. Brakes got better by the year too, 4 piston calipers came in around 99 I think. The 1997 JTX was / is a good bike, but it's a 10 year old trials bike, condition is all important. If you go to the Spanish GasGas website, you can call up details and photos of bikes from most years. Quote Link to comment Share on other sites More sharing options...
