  • Beta 390RR 2019 Long Term Review

    Beta 390 RR 2019

    This is my second 390RR. The first one a 2015 carb model I sold at 10000kms.


    Here is a report on my Beta 390RR it is now 12 months old and I have done 200 hours and 4700kms
    The bike is always transported to the trails and transported back home again.

    I fitted radiator guards, steering damper, Tubliss front and rear, Shinko 525 Cheater 120 size to the rear and a Shinko 216. 100/90/21 fatty up front.
    TMD chain guide. Fan kit also. Bark Buster hand guards. Tug strap.
    Spares are carried under the seat and all tools are there also except for a pump in my backpack. Tyre gauge and secateurs in two special pouches next to the steering head.

    Weight ready to ride full tank of fuel 122kg on my untrustworthy bathroom scales.

    After a couple of rides I removed the rear brake pads as they were far to sensitive and lacked feel. They were replaced with cheap non/low sintered pads which turned out to be perfect.
    These pads lasted over 1000kms.
    The front pads are still the originals and are now getting a little thin.

    24hrs
    Changed fork oil and added a .10mm shim to give mid valve float.
    The fork action was not plush and this modification made the forks very good.


    Engine oil Penrite 15/50 full synthetic and Gearbox oil Penrite 10/40 full synthetic is changed every 500kms

    50hrs 1100kms
    Instrument battery replaced as instruments were dodgy when engine not running.

    66hrs 1550kms
    Fork oil removed and the Sachs ZF forks upper anodizing on the inside of the legs had worn off already.
    New upper legs and seals and bushes supplied under warantee.
    Fork legs then sent to Japan for Kashima coating at my cost as I didnt want them failing every 1500kms.

    The bike is now very easy to ride and soaks up the trail trash with ease.
    The engine is brilliant no unexpected power and never not enough power.
    I tend to ride in as tall a gear as I can get away with and slip the clutch a touch if needed.
    The clutch is easy to use and never complains.
    The rear suspension still feels a little harsh but not as bad as when it was new.

    Starter button failed. (Ark-ed contacts.)
    Instrument panel failed completely whenever the bike was not running.

    Checked all linkages and all appeared to have enough grease except for the bottom shock bearing. All repacked and reassembled.

    The starter seems very slow to turn over occasionally and battery never seems to get much higher than 13v. Lucky it starts first go every time.

    87hrs 2000kms
    Replaced front and rear Shinko tyres with the same 216 front and 525 rear.
    They have both done 2400kms as I removed them from my 2015 Beta 390RR before I sold it. The front had cracked most of the knobs on the edge of the tyre. 11psi.
    The rear was worn but traction was still awesome. Normal pressure was about 6psi

      93hrs 2120kms

      I was getting sick of the Beta 390RR Lithium starter battery running on empty all day. I would start the ride with 13.3v and after 40 minutes it would be down to 12.7V or less.

      Dropped it off at the dealer for them to fix it.
      Got it back after 3 weeks with a new stator.

      The new stator did not fix the poor charging.

      Fitted my Kashima coated forks and 5wt Motul oil.

      While waiting for my Kashima forks to turn up I rode with 2015 Beta 390RR forks in my 2019 Beta

      108hrs

      Bike was constantly at around 12.4V on hot days with the fan cutting in. The headlight has never been connected for months.
      Back to the dealer again left there for 10 days^frt to fix the non charging issue.
      Got the bike back they admitted there was a problem but could not find a fault.
      While the bike was on the Beta diagnostic/scanning tool I could see that the bike computer had done almost 6000 minutes.

      124hrs 2800kms

      Changed the 2 plastic oil pump gears.
      Valve shims adjusted and reset.

      134hrs

      I asked and received a new rear wiring harness under warantee to see if that would fix the poor charging issue.
      It made it little better but not fixed.

      As I now had obtained a wiring diagram for the 2019 Beta 390RR I decided to cut the sheath off the harness and solder up the 3 cold crimps under the rear of the tank and 2 more next to the steering head. All 5 cold crimps looked perfect no corrosion or dodgy crimp around the wires.
      Soldered them all and now have battery at 13.5v always, and I am now riding with the headlight on permanently. Fixed!

      145hrs

      Flushed Front and rear brake and clutch fluid Dot 4
      New rear brake pads

      159hrs 3600kms
      New chain and sprocket now 13T 50T

      Fork oil change Silkolene RSF 5.
      Filled to nearly 135mm from top. C 6 Reb. 9

      Depending on the ride I get about 14+ kms per L per tank average.
      I have got up to 17km/ l and as low as 11 in tight nasty single track where it feels good to change into 2nd occasionally.
      The bike is smooth with nil vibration.

      Now one thing I have to be aware of is that the Beta apprentice that was given the job of fitting the fuel pump pick up, for the dual injectors, put the pickup not on the floor of the tank but on the front wall of the tank.
      This means that with less than 600ml of fuel left going UP a steep hill the pick up is out of the petrol and the bike stops.

      A normal person would put the pick up on the back wall of the tank if they couldnt fit it to the floor.
      If it ran out of fuel going down you could coast to the bottom of the hill then ride away.

      The map that was loaded when new was FMF +200.

      I always ride on the "Rain" map

        What rear pads are you using as I'm trying to find some with more feel than the Beta OEM?
        Thanks.

          Here is a link to the exact pads I am using from APEX Imports. (I have now stocked up with 6 sets) For $2.76 a set plus postage Im very happy.

          SKU: BP367

          Apex Imports; https://www.apeximports.com.au/brake-pad~6948

          I have been using their Oil Filters in my last 390 and am now using them in this 2019 Beta 390 RR.
          Some people may turn their nose up at a cheap oil filter and pay 8 times more for genuine or aftermarket filters.

          I have stocked up on them also. They are on special $2.27 each at the moment.

              Those are two quality reports Jallopy. Thanks for that.
              You seem to ride like I do... Tearing knobs from edges.

              Just a thought; maybe consider a second earth strap.

                  Tearing/cracking Knobs from edges is a design fault of the tyre in my opinion,or maybe you and I are riding terrain the tyre is NOT designed for.

                  Tried 2nd earth strap off the rectifier/regulator it is not the problem.

                  Solder the 5 splice joints and it is fixed. I also added thicker bypass wires but in hindsight it is not necessary.
                  Solder the 5 splice joints is now a simple fix for poor charging on the EFI 4 strokes worldwide.

                    They are good honest dealers.

                      Beta 390RR Review

                      165hrs 3760kms

                      Fork oil change. Oil colour was normal when drained.
                      Silkolene RSF5 went back in. 135mm from top.

                      New front tyre. I m trying the Golden tyre 216 Fatty.

                      188hrs 4400kms.

                      Rear Sachs shock Oil change. The oil was dirty as the shock cylinder was starting to wear.
                      Replaced oil with Golden Spectro 85/150 and set the pressure to 145psi (Down from 155psi) The shock seems to have lost the harshness on square edge hits.

                      Chain and sprockets replaced. 13T front and 50T rear.
                      Up from 49T. This combination makes second gear more usable in slower trails. I rarely now go back to 1st .... just feather the clutch a little and then let the torque of the 390 do the rest.

                      191 hrs 4470kms 27.09.2019
                      Rear Shinko 525 Cheater , replaced with the same tyre. I got over 2400kms from the this Shinko.
                      That rear Shinko tyre is awesome soft sticky rubber and it last and lasts. Very good grip on rock wet or dry. Pressure from 4 to 8psi in the dry.

                      The bike is comfortable, easy to ride and rarely gets knocked off line. Starts first go every time, even in gear, doesn't miss gears or have false neutrals.
                      Gearbox oil always comes out clean The engine oil is a little dark after 500kms. The seat could do with a softer foam padding.

                      I have now done over 200hrs 4720kms and cant wait for the next 200hrs

                        Thatís excellent wear from that Cheater 525, it amazes me how well they still hock up even when worn down low.

                            Great work, Jallopy.

                            Have you tried a GT333 on the back & if so, how do you rate it compared to the Shinko?
