    520 RS / 498 RR vs 500 RS / 480 RR

    Also, I should mention that my bike's suspension has been fully worked by Stillwell - so there likely isn't a lot to gain for me in regard to suspension unless I were to pick up a used bike with similar work already done. Thanks again for all the responses. It's amazing how much more productive a conversation can be had within this section of the forum with the adults here vs say the Honda 2 stroke section of the forum...

    520 RS / 498 RR vs 500 RS / 480 RR

    Thank you all for the responses & your input. & yes, my 2013 520 RS *DOES* have a 6th gear... Perhaps your friend is running lower gearing on his sprocket choices? That can make a significant difference. I'm running stock gearing & the engine revs have never bothered me at highway speed. My old XR650R used to be revved to the moon on the highway. I too am in position where I could likely sell my bike & add around $2000 to pick up a 2016 or so used 500 RS - but I am uncertain that the step up would really be worth that investment. I'd LOVE to make the switch to the later style bodywork, as that is one of the things that entices me to jump to the later model. - especially with the additional options now available between with Polisport plastics & several different graphics sets available. I almost did it awhile back, but ran into a significant hangup. The older bikes also have a completely different set of side panels (airbox covers) & the lines do not match the newer rear fender assembly on the right hand side (if my memory serves correct there is an extra piece of plastic that juts outward you must trim off via dremel) - but even worse, there are no graphics available that will fit properly & cover those side panels. If anyone here knows in more detail the specifics of that mod, I'd be interested to hear further details. I found limited info before but abandoned the project fairly quickly after realizing I was never going to find a set of graphics that fit the bike properly if I did that....
  3. First, I must state that I love my 520 RS, but very much dislike Beta's misleading model/engine size designations on the RS models. Why on earth have the Italians designated my 498cc bike as a "520" or the newer 480cc RS models as a "500?" But with that out of the way, this is what I am wondering about: Aside from cosmetic changes, are there any significant upgrades to be had in stepping up to the later 500RS models over my current 2013 520 RS? Obviously, I am fully aware of EFI on the later bikes - but is there anything else of significance in regard to the engine or handling characteristics? Are the 498cc & 480cc engines comparable in terms of power output & delivery? Does either have a clear advantage over the other in that regard? The 2013 520 RS, as many of you may know was the last year of the older body style. I love the bike, but I've come to a crossroads on whether or not to invest significant funds into getting the bike dialed in exactly how I've always wanted, or stepping up to a newer model 500 RS & dialing that in, instead. I oddly would kind of prefer to stick with the carb setup over EFI - but I'm certainly not dead set on either one, as they both come with their obvious advantages. Advice or experiences from those who have ridden both models of Beta would be greatly appreciated.
  4. I've run into a bit of a problem trying to find some oem replacement graphics for my 2013 520RS. For whatever reasons, Beta does not have parts diagrams online for 2010-2013 RS models. For most items, I have been able to refer to the 2012 RR parts diagrams to get the correct parts - but I am unable to do so in this case, as the graphics would have "RR" markings rather than "RS" as well as the possibility of getting the incorrect graphic scheme all together, due to some discrepancies I've noticed in the parts diagrams. Does anyone know the correct part # for my 2013 RS graphics, or know where they could be obtained? I've contacted a Beta dealer who's answer was "you'll have to run the 2010-2012 RR graphics" because he too does not have an RS-specific parts diagram, or any way to obtain the correct part # for RS graphics. I've also contacted Tom @ Sierra Motorcycle Supply, who has been helpful so far - but he also does not have any RS-specific parts diagrams available. He said that my 2013 is supposed to have white plastics..... I have attached a pic of a 450 with the same graphics as my bike for reference, but for whatever reasons is it not displaying at all.

    300RR Powerband vs other 300s?

    I just rode Carnegie for the 1st time a few days ago... I saw over half a dozen Betas while there

    300RR Powerband vs other 300s?

    Thanks guys for all the responses. Lots of great info in this thread. After reading the responses here, I'm leaning toward a 300RR (or any other 300) maybe just not being the right bike for me & my desire for aggressive, arm-ripping power delivery. To give a small amount more background on myself, I've been riding for over 25 years & have grown very accustomed to man-handling large 2 strokes. YZ490, CR500, KX500, etc. I am so accustomed to that type of power that anything less honestly bores me to some extent. I used to sort of hate 4 strokes with only a few exceptions (TT500, XR600R), prior to the introduction of the super hard-hitting YZ400F & YZ426F which most people seem to think were too aggressive on power delivery (I loved mine). I ride mostly trails anymore on tight single track in sloppy, muddy, rooted up technical stuff. No significant time spent on mx tracks anymore, & when I do go, it's just playing around - no serious racing.. I have entertained perhaps running a few hair scrambles & would likely qualify as a fast B rider if I do. As previously stated, I do fully realize that the power delivery I'm looking for is completely counter productive to my riding environment, & that the 300s are actually ideal for what I'm describing. I'm still not discounting the 300s quite yet, simply due to that fact. Is there any particular 300RR pipe which moves the power curve a little further up the rpm range? On the KTM for instance, people seem to say the Pro Circuit pipe & red PV spring completely change the way it delivers power, making it more pipey.

    300RR Powerband vs other 300s?

    CR500 in a Beta chassis.... Oh yes, that's definitely my style bike ::drool::

    300RR Powerband vs other 300s?

    My 520 RS was delivered through them... I did not buy it new, but the previous owner had all positive things to say about the shop & staff.

    RC Timing/ Duration tweak?

    Thanks for the kind words, Mikie1! & yes, I'm super happy with the bike... I will definitely be adding a programmable ignition in the near future, soon as my wallet recovers from the holidays & such Will report back the results once it's installed.

    300RR Powerband vs other 300s?

    His bike has a fresh top end with a few rides on it. Was running yellow PV spring (swapped to red after that ride.. Not much change, really) & FMF gnarly pipe. He says the jetting seemed spot on when he pulled the plug as well.

    300RR Powerband vs other 300s?

    Yes sir, hundreds. 5+ hours away. Klamath Falls, OR is the nearest dealer @ 260 miles from me. Next closest is 300 miles away the complete opposite direction in Vacaville, CA. I've called previously & neither are offering demos.

    300RR Powerband vs other 300s?

    I've been dreaming of owning a 300 2 stroke for quite some time. Husqvarna, KTM, Husaberg, or Beta. Beta of course being at the top of the wish list I had never ridden any of the brands 300s for more than a couple of minutes, up until a few days ago (never got opportunity before). My friend picked up a 2008 300 XCW & we switched bikes for an hour. While the 300 was extremely manageable & I could find traction seemingly under all circumstances, I was left underwhelmed with the overall engine performance & the way it delivers it's power. I was mostly outright disappointed with it's soft power delivery & lack of "hit" when you get into the upper powerband. The power delivery felt too linear & 4-stroke-like for my tastes, being used to riding a CR500AF & other hard-hitting 2 stroke mx bikes, mostly. I fully realize that the explosive, wheel-spinning 2 stroke powerband hit is NOT what the KTM is all about, & it's counter-productive to have that sort of hit on a woods bike anyhow. But the 300 was also much slower than I ever expected, as well. I had switched bikes with my bored & stroked CR280 & it absolutely destroys the KTM in acceleration & raw power (they weren't even remotely close). I came to the conclusion that if all the 300s have that same extremely broad powerband with no hit, as well as slower acceleration vs a 250 mx bike, a 300 is probably not the bike for me. Does the 300RR deliver extremely broad power in the same manner that the KTM does? What about the 250RR or Xtrainer? I have opportunity to sell my CR280 to that same friend & finally pick up a 300, due to him also being underwhelmed with the KTM for the exact same reasons. Wish I could just demo a bike & find out for myself, but that's an impossible option due to my location (nearest beta dealers are hundreds of miles away).

    Drag Race: 300XCW vs CR250R

    No doubt it's not a completely straight forward comparison... I did forget to mention that my CR250 is completely setup for the woods with heavy flywheel weight, 3.2g tank, rekluse, etc. Aside from the transmission, the two bikes share many characteristics. Weight is obviously lower on the CR though as well. Do you believe that a 250sx would dominate the 300XCW in the same manner my CR does, in a drag race? I'm genuinely curious, as I have not owned a 2 stroke 250 in 15 years or so. I ride a Service Honda CR500AF normally & the 280cc CR honestly doesn't feel too far off, except my 500 is geared much higher & probably has a 20+mph top speed advantage.

    Drag Race: 300XCW vs CR250R

    The Max Power RPMs 280cc setup consists of a stroked crank as well as an oversized & offset bore.. I realize it's an apples vs oranges comparison (Red vs Orange.. LOL) but definitely appreciate your input!

    Drag Race: 300XCW vs CR250R

    A couple of days ago I purchased a 2003 CR250R from another forum member. The engine is an absolute beast, as it has a Max Power RPMs 280cc kit installed, a PWK air striker carb, & Boyesen RAD valve. I picked the bike up basically as a less expensive & lighter Honda alternative to getting a KTM, Husqvarna, or Beta 300 2 stroke. My friend has a 2008 KTM 300XCW, so we decided to run some tests. I suspected the CR would smoke the KTM, but I did not figure it would be by very much. I was pleasantly surprised to discover how wide of a performance gap there was between the two. I am also approximately 40lbs heavier than my friend, & we ran drag races multiple times from both dead stop & roll-ons. The KTM had absolutely nothing on the CR. EVERY time, the CR overtook & walked away from the KTM. I even gave him an approximate 30ft lead once, & still just blew by him with little effort. I was convinced something must be off on his bike to have such a wide gap in performance, so we switched bikes for about an hour. The KTM seemed to run just fine - it just doesn't make the power that the heavily modified CR does. He's running the green powervalve spring. My friend was left speechless, & is now trying to convince me to sell him the CR or trade it straight across for his 300 - which from a financial standpoint, would make a lot of sense for me to consider. To any of you who have heads-up raced a more stock CR250R against a KTM 300, did you get similar results? I'm still wondering if there is something not quite right with his bike, or if my 280cc stroked engine is really just making that much more power. I'd like to tell him to just go find a CR250 & buy it, but uncertain if it's going to perform anywhere near the level of mine vs his current bike.
