    There are definitely better bikes out now than my old XRs, but only about 30 lbs lighter. I am hoping for an 80lb reduction. I tend to over maintain machinery and have had to make no repairs in 17 years of owning my Hondas. I know just what you mean about a 250 at highway speeds, kind of sketchy, like riding in sand. But I’m used to the 250 in sand even in 2nd gear, keeps you on your toes, but I’ve done a lot of it. The 300rr with the wide rear tire and light weight is intriguing, and I can’t wait to try it on the rocky trails. A few pm’s say it is doable in sand, but nobody’s first choice. As long as there are no big surprises due to the shorter wheelbase and different caster angle. Worst case is i would have to haul it to the trails in my truck, and ride an xr in the sand. Kind of a win/win situation (wife may not agree). But still looking at all options. I have a couple of more weeks to decide.

    Standard service of the 300 RR is 15 hours, and unless your thrashing it based on the 30 hour recommendation of the older 250 4RT's other than changing the air filter sooner in the dustier conditions of sand riding I would expect you could easily change just the oil at 15 and the oil filter at 30 without having any trouble. (Not recommending this just suggesting it as workable if one needed to)

    As for transmission oil, it's the same recommendation for the 300RR of 15 hours and 30 on the older 250 4RT and when I have changed the oil on that at 30 I am sure I could easily have gone 60.

    I personally think the 15 hour recommendation is for people doing heavy competition riding...

    My opinion...

    For the transmission are you using the Elfunobtainium or is Valvoline Dextron VI working out ok in the newer machines?

    Some good footage of Amos Bilboa riding the 4Ride at SSDT...No sand though!
    I still wish Honda/Montesa would bring him over to ride NATC! Amos wanted Mike Komer to move to Spain and be his minder, back in the day.

    Because I compete I run the ELF. I have heard of several using Maxima MTL 75 with good experiences though.

    ELF. It works perfect and can be purchased from your Honda dealer or Dennis.

    You won't need to be in a hurry to change it.

    Only crazy Honda people would be able to justify having to pull a case cover to change the oil, lol ;)

    :rofl

    I got 4, 4 liter jugs when I got my 07 4RT and didn't like the Maxima MTL 75 as much as the ELF so still running the HTX 740... What do you run in your 4RT?

    Probably just whatever is gurgling up by the pump. I am sure he is getting his fuel free just a few miles out of town with all the oil pumps surrounding him. In reality he was a pure breed Honda mechanic. It has to say Honda on anything he buys except for the Mopar!

    Motul synthetic 10/40 Transoil. Been using the stuff for years in the 4RT and all my 2-stroke transmissions. :thumb



    The oil and gas industry is 60 miles from here, minimum. 'Round these parts is farms, ranches, and dairies, dairies, dairies. I don't run what gurgles up from them in anything. :lol3

    I finally got mine out in some sand washes yesterday and it was a hoot! The low pressure trials tires just floated over the sand.

    If I had been going a little slower and it had been more open and less rocks on the sides of the sandy sections I was in I would have agreed with the term hoot. Really wasn't to bad, but chasing some fast dirt bike buddies wasn't as much fun as it could have been for me. :dunno

    Finally got out for my first ride of the year and noticed a bit of fuel around the cap, turns out the gasket had torn so it would leak a bit when the fuel gets sloshed up in the tank. (Like when falling over):muutt
    Once back home I remembered that I have an aftermarket cap that came with my 09, this one has a check valve in it that only allows air into the tank to prevent a vacuum but the factory valve on the bike seems to allow air both ways. Is there any harm in the tank building pressure as it would because I know how warm the tank can get in hot weather? Will try it this weekend as I plan to go to a two day event in WA.... Anyone seen one of theses caps used? 5F174BE7-0055-415B-8D89-439E030AF3DA.jpeg

    I was at the dealership yesterday looking at a 2016 Repsol and 2017 300rr. They both have a sticker stating “does not conform to epa noise & emissions, no offroad recreation on federal lands”. Has anyone had a problem using one in the usa on federal land with a spark arrestor installed?
