The stunning new 2020 TXTGP is now in stock here at John Shirt Motorcycles Ltd. We have 125GP 250GP and 300GP here and ready to go for immediate sale!

Each bike is fully prepared (not just pdi’ed) by the most experienced GASGAS Trials mechanic @factorykev24 Factory Kev here at JSM.

Each JSMGASGAS TXTGP (not 125)will also come with an extra supplied, fitted (and advised) low compression S3 head insert at no extra cost. The 250 and 300 have an S3 two-piece cylinder head with interchangeable inner head inserts. They come standard with the high compression insert which in our opinion is too much for UK riders and weather. We put the gold low comp insert in which makes the bike run so much smoother. You get the high comp insert with the bike but we advise not to use unless you are going to TrialGP! Kev also re-jets the 300.
