    LOL. Depends what you do with the engine, racing a YZ250 45+hp.. Dont use a cheap Con Rod when you rebuild it! This happened to a mate's YZ250 at a race weekend.

    Buy good, and look after it and it wont eat itself.

    @declan I'm building a SM YZ125 AF, I'll let you know how that goes.

    Keep it real

            @minia it’s so bad I don’t even think it was the cheap rods fault to an extent more of a manufactured fault very rare occurrence?

              @declan Perhaps. KTM has been known for engines blowing up, especially on their 690. Unlucky mate.

                @minia I’ll agree with the older big bore bikes but I’m a fan boy and ktm is my dream bike so I can’t agree on the other bikes I think it’s a bit unfair since ktm Make arguably the best mx and enduro bikes

                  @declan KTM certainly make some good bikes, but I view it more as a fashionable brand now than a business and it is not a brand I wish to be a part of. I've seen far more accidents and crashes on KTMs than I have on any other bike, from personal experience.

                    @declan For me, it's the whole picture

                    KTM's do make superb bikes, but you have to pay a premium for it. For the money, you can get a mint YZ or a CRISP DTR with lots of change. So you have to weigh it up. If money wasn't an objective.... but unfortunately it is. This is why I love the Aprilia's RS and MX. You're getting fantastic spec'd machines at a DTR price. So it's the best all round.

                      @calum but then the insurance is sky high atleast for me it is kind of like an Impreza rally car for 500 pound really cheap but that’s because the insurance is around 4K

                        If you want the BEST stock enduro, road legal and incredibly cheaper than a KTM, Gas Gas EC or the later Beta rr enduros. As far as im aware a Gas Gas EC 125 from 2000 odd + makes as much power as a modern MX bike and are reliable engines, the stock components are incredible as standard too, the new models come with FMF pipe, v force reeds etc. I had a Gas Gas TXT Pro trials bike a few years ago and it was stunningly built, if they werent so rare id drop my DT for an EC in a heartbeat.

                          @glynn123 Sorry, as much as GasGas may build good engines they aren't nearly as reliable anywhere else. And parts from their older bikes can be very tricky and costly to find, as a GasGas owner I really can't recommend it. Not unless it is their newer models.

                            @minia my friend got a 2012 ec125 since he didn't enjoy his duke 125. The transmission blev up after the 3rd ride or something. The bill was huuuuuuge. The workshop going to fix it still has it and they are awaiting parts from gasgas. Obviously he don't know anything about engines or stuff. Not about how they should be driven or how they should be serviced.

                              In the 3 years I owned my Gas Gas trials I never had a problem, changed the clutch and piston due to my riding style being heavy on clutches. Parts were easy to find and reasonably priced in my eyes, and it was just fantastically built and designed. To this day my favorite bike ive had, really regret the sale.
