    Thunder Valley went from fun fun. To HOLY SH!T

    As of 10/30 they've neutered the track a bit. The former quad jump coming out of the gully is now more of a step-over tabletop. Its very forgiving. There's less of a difference in speed between rollers and jumpers, making it safer for everyone. Lots of novices and a good 80 rider were clearing it. Riders who landed horribly short were rolling away unharmed. The triple going down into the gully has a more forgiving landing and is now more like the old stepover that was previously in this section. Its still a challenging jump, but the landing seems less critical. Most of the rest of the track is about the same. The triple step-up in the middle of the track is still there, but doubling it is a pretty fast line with decent flow. The 110+ step-up/tabletop at the southwest corner of the track is relatively unchanged, but still pretty safe for a jump of this size. You have to rail through the preceding corner perfectly and hit it with every bit of 3rd gear on a 450 to clear it. Lots of people were landing short and rolling away unharmed. I've not been able to over-jump it no matter how hard I try.

    Thunder Valley went from fun fun. To HOLY SH!T

    I agree that Thunder Valley is Colorado's black diamond motocross track, and I can sympathize with riders who lament the fact that it went from a C/B-rider track to an A-rider track virtually overnight. Personally, I like having the opportunity to test my skills on the same layout where the best in the world compete. It attracts the best riders in the area, keeping tracks like IMI and Watkins more mellow and less competitive. Everyone wins in this respect. Most peewees and all quads go to other tracks, making Lakewood a safer place for fast riders to practice. The crowds at Lakewood suggest that there are plenty of skilled riders and budding racers around to keep them in business, and there plenty of other tracks to ride if one is looking for a kinder and gentler riding experience. Its nice to have options.

    How to ride a freshly disced track?

    Stay on the gas as much as possible and keep your weight a little farther back on the bike than normal. Do most of your braking in a straight line because if you use progressive braking through the corner entrance, the front end tends to knife and dig into the dirt. In many corners, you don't have to brake at all. The bike slows down very quickly in the heavy stuff when you simply let off the throttle. You have to be very smooth on corner entrances or the front end will dig in. No squaring or sudden changes of direction mid-corner. Try to float through, not knife in.

    3rd gear jump 4th gear pinned

    The most important thing to do on a big flat landing is grab a handful of throttle so you are accelerating hard when your rear wheel hits. The chain torque stiffens the rear suspension significantly, which helps to prevent the suspension from bottoming violently.

    How's the form?

    Good solid riding overall. You could be more aggressive on corner entrances by braking later and drifting in instead of coasting so much. Work on modulating your brakes to set up a controlled drift. You'd get better drive out of corners and onto the straights by clutching more to keep the motor reving.

    Thunder Valley

    Rode TV on saturday. The new 115' jump is fun and very forgiving. I came up short a few times while gathering the nerve to clear it, but I never came close to crashing or hurting myself. Third gear pinned on a 450 after sweeping the widest line through the preceding corner worked perfectly for me. IMO, clearing the big step-up from the inside line is harder.

    DNA Extreme Wheels???

    I have Pro Wheels on my 450. The rear cracked through the seam in less than 20 hours, but they replaced it under warranty. I'm pretty hard on wheels and have cracked several of the stock DID rims on my CRFs over the years. In my experience, Pro Wheels are no stronger than the stock rims, but the serations around the rear rim are an improvement over the stockers because they stop the tire from slipping on the rim. I'll be putting A60s on my next bike.

    fly wheel removal

    I've used a strap oil filter wrench for a car to hold the flywheel while loosening and tightening the nut. The tool for removing the flywheel is cheap from Motion Pro. Before buying one, I tried a standard flywheel puller and put a penny on the end to protect the end of the crank. It didn't work and I had to drill copper out of the oil pass hole.

    It's Here...the 2010 YZ450F

    My interpretation of P Foster's review comes from his comments about how cornering the YZF "took a little bit of getting used to" and that you "got to actually lay the bike down into the turn". When he used the qualifier "not necessarily in a bad way", it struck me as sugar coating. He compares its characteristics to "most bikes", not necessarily four strokes or even 450's in general. http://motocross.transworld.net/videos/2010-yamaha-yz450f-press-introduction/2/ Cornering comments start at 2:15

    It's Here...the 2010 YZ450F

    Guess I touched a nerve. I'm not bashing the YZ450, just trying to get some objective riding impressions because its one of my two choices for a new bike. P Foster's comments about its weight relative to cornering reminded me of how much easier my 06 CRF450 would lean or drop into corners compared to my 02 CRF 450 or my 01 YZ426.

    It's Here...the 2010 YZ450F

    Trying to read between the lines of the early ride reports. In the Transworld video P Foster makes it sound as though the bike doesn't drop into corners very easily. His tail end gets kicked out on two corner exits in a fashion that is odd for a rider of his skill level. MXA is pretty tight lipped about its handling, and most everything else about the bike for that matter. Cycle news gushes about its handling but criticizes its herky jerky power delivery and difficult starting.

    How Many Preload When Jumping?

    Most jumps have a long enough approach that I'm doing the opposite of a preload and using my legs to absorb the face of the jump instead of springing off against it. If a jump doesn't quite have a long enough approach or I take an inside line to make a pass, then I'll preload or seatbounce to get more distance. Usually, I can get more distance preloading, but the seat bounce technique is easier when there isn't much time to get off the seat.

    Always running - can't seem to chase

    Maybe try riding multiple-lap motos in practice and strive for lower overall times for the whole moto instead of just worrying about how fast you can go for one lap. Riders up front often make mistakes that put them on the ground for a few seconds. If you charge hard through a whole moto your chances of passing and staying ahead of a downed rider are much better than if you settle into your position and cruise. If a rider from behind sees you cruising and he can see that he is making time on you, he'll charge harder to reel you in. Its better to keep the slower riders back farther behind you for the same reason you want to stay as close as you can to riders up front. Another thing to consider is that the rider who is in front who seems a little faster may actually be a slower rider who is riding over his head. If you put enough pressure on him to keep riding at that level for a long enough time, he'll eventually make a mistake.

    Look what Yamaha has done

    Its nice to see Yamaha trying something radically different, but I remember the Cannondale and the 97 CR250 too well to plop down eight large on something that only looks good on paper at this point. Red and blue have always been good to me. Yellow and green, not so much.
  15. That's what I'm trying to find out, if the 2010 has any internal improvements not addressed by Honda that might make the price difference over an 09 worthwhile. Personally, I find it very odd that they would make internal changes, then release a bike that has absolutely no cosmetic changes from the prior model year. Its as though they are trying too hard to make us think the 2009, of which they have lots in stock, is an identical but less expensive 2010 model.
