  1. I’m looking for a Shop manual for the 16 TRS 300. I found a user manual but it doesn’t have enough detail.
    Thank you!

  2. Hi Steve,

    Just bought a 250 RR and i have a clutch judder. I have just run it in so will change the gearbox oil and see how I get on over the weekend.

    Are there any known issues with this judder?



  3. Hi TRS UK

    My superb 250rr needs a front fork fettle now that they are bedded in. What tool do I use for the adjusters underneath the bottom of the fork legs ?


  4. Hi. Im thinking of buying a 280 an then a guy at a practice area said they have had big problems with gearboxes, its kind of put me off a bit..
    Is this the case

  5. Hi Steve, I have noted in the comments how to drain and re-fill the engine oil but with reagards to levels…

    Bike is 250CC RR.

    Do you suggest putting the bike at an angle when draining to get as much as possible out?

    How much should I be putting back in?


  6. Hi Ryan,
    The 280 is very smooth, the carb alone would make the bike aggressive but the re map cdi and reduced crankcase compression compensates for it the bike is still very rider friendly.

  7. I need to change engine oil, do you use light gear oil 75w such as putoline ? I have always used atf in my previous life as a Gas Gas owner

  8. Will the 280 RR ride as smooth as the standard 280 one. Does the carb and different mapping make the power to aggressive. Thanks.

  9. Would you know of anyone who has made a flywheel weight for a TRS? I know it would have to be custom..just thought to ask..Thank You!

  10. On my bike there is no sag at the rear, but also no hard knock when it comes back. I will try with 15mm.
    Thank you very much Steve.

  11. Hi Hari,
    The rebound is the screw at the bottom of the shock, by the linkage, you can make the rebound faster by screwing this anti clockwise.
    the compression is done via the purple knob at the top, again anti clockwise for softer damping. 15mm sag with bike under its own weight for me this is very important.
    hope this helps.

  12. Hi, thanks for the quick answer.
    I got my bike already with the Reiger.
    At the moment it feels to stiff and also a little to slow (rebound) for me. I have less than 70 kg.

    If i remember right from my previous bike the purple knop is for compression and the little one is for rebound. The problem is i don’t remember which direction i have to screw it :-).


  13. Hi,
    Thanks for the question. The bikes currently come from the factory with the Olle shock fitted, we can however fit the Ohlins or the Reiger for you. Before you receive the bike.
    There is a Raga rep/factory model coming out in January. I am sure this bike will have the Reiger fitted as standard. This bike will be launched very soon at the Milan show that starts on November 8th.

  14. Can you order the bike from the Factory with the upgraded rear shock or must you add it yourself later? Cheers

  15. Hi Harald, We have little experience here at the moment with them.We have just started running one on my sons 250 He is quite light weight and all I have done is set the sag at 15mm under the bikes own weight.
    The damping adjustment is a difficult one as everyone likes it slightly different. Are you have problems ?

  16. TRS Fuel Tank
    We recognise there have been some fuel tank issues, we have supplied new replacements under guaranty as you would expect.

    These have just been replacement with the same item.

    It has taken a couple of months to understand what has been wrong as this appears to be mostly a UK issue.

    We now have a new design tank out on test with genuine customers as well as team TRS UK bikes. Results so far are positive.

  17. Do you have any technical info for the Tech Forks .. service and set-up etc

    cheers, Jason Gregory

  18. The oil drain is just bellow gear lever on the left hand side.silver Allen bolt 6mm Allen tool.

    The fill is above sprocket just to the side of the carburettor

  19. Hi there, just run in my new TRS, I want to change the gearbox oil, do I drain from the hole right underneath, and fill from the plug near the front sprocket?
