    The pictures of the engine put against the frame, and the engine itself, earlier in this thread, are of the KTM based version.

    They are doing 'market research ' to gauge the interest.

    It should be pretty high, given the amount of YZs out there, just as there is / was with the pre '17 KTM. At this point in time, there would be far more potential sales for a YZ version, than that of the '17 and onwards KTM. I don't think they have done the later model KTM kit, yet.

    It's entirely logical for them to use what they've already made, the 89mm ( using CR500 piston and Rod Kits) x 83mm crank set, for the 516cc capacity it is now. Barrel , Head, etc, etc.

    Yes, a potential 400 / 430/450 would be wonderful - much more to my preference ( well, 350cc would be fine and dandy, as well ) - I ride a modified CRE500. Heck, in the later years of the 500GPs, quite a few CRs run by privateers were reduced capacity 500s, to "around' the 400cc mark. Christian Burnham ( a Brit privateer, that could make a living doing GPs and Internationals, who then went on to running the Belgian MX series for a number of years) , in an interview years ago, said it was his favourite version of the CR. A 'squared up' CR500, is just under 390cc, but I think they were more in the range of 410 / 430cc.

    An 83mm squared BRC would be 464cc. But, as I wrote, I doubt that they would not use what they have already. Now, a de-bored, below 83mm, version, using the 83mm crank, would be a weapon - consider the bore and stroke of 250s, people = undersquare. But, they'd have to source/ make a piston and sort the barrel bore and porting.

    On their Face Book, where they've run the idea up the flag pole, just as they did with the KTM version, a fellow put forward his views on the gearbox problems with the YZ, for which they thanked him. If they are genuine ( I think related to the shift forks and drum?), well, BRC could easily deal with it.

    They've a way to get more use for major parts they've developed / made / sourced. It's entirely logical.

    Good on them.

    They could / would broaden their access to a base of people devoted to / having a current bike, who want something bigger, and different.

    As for the YZ chassis being inadequate? Well, the KTM / KTHusky ones have proved to be adequate, and they are not anything special, compared to the YZs, if you can put aside prejudices you may harbor. I've repaired quite a few KTM chassis over the years - I've yet to have had to do so on the YZ250 chassis ( I have, of course, heard of / seen on sites, some issues) - I've done a few 4T YZs though - cracked welds, mostly, and, ripped top subframe mounts. I've put my TIG torch to pretty much all brands chassis, over the decades - things do tend to 'cark' it, whatever brand they are.

    It's a bit of money, the price of the BRC 'Open Class' kit, but hell, really, it's buggerall, to quite a few. Most of my friends clear around 2K a week, and they buy plenty of toys. At least 3 of them, with current YZs and YZXs, would jump on a kit, such as the BRC, promptly. Especially if it incorporates a 'Magic Button'.

    I dont get all this "chasis" nonsense. You really telling me that a y z250 chassis from 10 years ago is that much worse than a newer bike? 250x is fine if you ask me, hows this different?

    I love YZ250s almost as much as I love KTMs. I've owned 2003, 2005, 2006 and 2008 YZ250s. They all felt about the same after valving front and rear. I actually prefer the 2003 steel frame (with SSS forks) - it just seems to ride a little softer. This is presently one of my backup bikes. At the moment, it is seized. I loaned it to a 19 year old 'A' guy (whom I've known his whole life and he is a really great young man) and he seized it about 4 miles into the hare scramble. My fault - it was jetted for a 168 lb guy and the the 'kid' is 260 lbs if he's an ounce! I think he stressed the motor a little more than what I can do! I'm tearing it apart next week. I'm curious to see if it is the top end or the crank?

    Oh, Oh - I got my maths wrong, (I blame my Bear Paws fumbling on my 'phones tiny key pad ) an 83 x 83 would be a poofteenth over 449cc, so, 'legal' if ever equivalency was allowed in the major Championships......... I myself would still prefer a tad smaller, Modern, New 2t 450 class engine. The tuning possibilities and durability could be incredible with a 450, or smaller, new 2t.

    A bore and stroke ratio akin to a KTM SX250 2t (66.4 x 72) , with that 83mm stroke, would give you around a 390/400. It would be such a wonderful engine. Whoever did one.

    But, that 516cc set up will undoubtedly be it, if they get enough interest. Good to see them (hopefully) providing another avenue for those that want something different to most.

    Also, I was wrong on YZ250 chassis repairs - I've not done any Aluminium, 05 and up repairs, but, I did a few last year or near last year (I think) steel chassis repairs . Some had bad welds at the LH side swingarm pivot housing to upright tube joint on the outside - be it incomplete welds, or, indeed, the MIG weld having 'sliced' through the tube, with only the pretty blue paint covering the bad joint. Sometimes, set up and quality controls go awry.......

    This right here. I've always said if KTM would come out with a FI 400 two stroke, I would put my money down immediately!!

    I took the top end apart yesterday - the top ring had snagged the exhaust port. It didn't damage the cylinder; head and rod are OK. Plug looked lean which probably caused the problem. A new piston and jetting and I'll be back in business.

    You got lucky. Just curious, was the piston installed backwards?

    I checked the piston - the arrow was pointed toward the exhaust port and the ring ends were to the rear of the cylinder and moved between the intake and the transfer ports. Yes, I got very lucky that the cylinder and head were not also destroyed. So it's a $150.00 (for a new piston) mistake instead of a $500 - $700.00 mistake. The 265cc kit has about 50 hours on it. The failure was my fault for being lean on the main and turning the bike over to a 19 year-old 'A' guy on a grass track. Predictable outcome.

    I always heard the 700 was all low end and fairly tame for what it was. The 620 was the one that would kill you.
