It comes with a small sacrifice in power but is really easy.

There are other ways that would make more power (pulling piston out, rebalancing crank) but I believe the rules require no work be done below head gasket, so as to not make it a spending race.

If you need help, there are a bunch of us willing to show you how.

This is very valuable to me and I appreciate you taking the time to respond, I get home around late December, and I'm hoping to have a fun "return" year in 2019; so this appears as if it would make a suitable and cost effective way to enjoy some track days.

Something like this would be perfect, I'm not sure if PTT (or any of the other groups) have a 'tricylcle' group; but cost effective track time is definitely in my future.

I'll be home for a couple of weeks next month, a welcome break to the grind; so I'll begin looking for a reasonable 600 to Frankenbike; thanks so much for taking the time to respond and provide some guidance to some random dude

It's called B group if you're quick on your "little" bike, C if you're not If you're really fast on it, you can call it A group

It's been a few millennia since I turned a throttle, so I suspect they'll create a new group in my honor, the "D" Group "soap box Derby".

I appreciate the feedback, I recall liking riding with PTT so I'll give a go when I get home.

Madame, I do indeed thank you

Indeed I shall! But it'll be awhile unfortunately, next season even. But don't be surprised when I do

So what are the numbers looking like for the crippled class? Riders...

Seriously thinking about trying this out instead of 600 class. I took a 9 year break from racing and am eager to get back into it. I have a few track days scheduled for July and figured I would race Sonoma for my comeback.

Was considering getting an R3 to race but this class may be a better option as my bike is ready to race now. Trying to cut cost down on tires and want to learn to ride and not rely on power. Also my bike is a 2007 GSXR 600 so it may be more competitive as a triple than racing against modern 600 in the 600 classes.
Thanks for any suggestions in advance. I watched the AFM races last weekend and was dying to ride!

Freak,

I think there were about 8 or 10 of us last round.


I took a 10 year break from the track, rented a FLAP a couple times and knew I wanted to get back into the sport. I was looking for a built SV when I heard about the cripples. To me, it's the way to go -- modern package making 75hp has made me a much better rider than I ever imagined. If you are going to be at round 5, several of the 450's pit together -- come by and say hi. owen 423. PM if you have any questions or want to chat about it detail.

Time to bring this full circle...

Thanks to the utter chill-ness of Charles, #510, I got the chance to sample a well sorted '08 R4.5 Triple at Laguna Seca last weekend. And by sample I mean I rode it all day. If Charles is representative of the typical 450 racer then I definitely want to hang/race with you guys.

Sadly, I don't think I will be...as least not racing against.

For most people I think this 450 thing is absolutely the way to go. The bike still has plenty of squirt at the top end for putting a smile on your face and dusting SVs on the straights. But it doesn't wear out a rear tire anything like a 600, and that lower power is great for working on racecraft. Chassis is top notch, modern, race-proven stuff and parts are plentiful. Plus, as mentioned, the 450 crew seems like the best slice of racer-dom. And if you want to sell it later, the new Triple-ing method is all electronic -- flip a switch and it's back to a 600.

So why am I not going to get one? Because I'm weird.

Having come up riding and racing old, narrow, squishy, slack-geometry'd, low power, low revving bikes the adaptation to a true modern supersport chassis and powerband is difficult for me. Assessing my day at Laguna I came to the conclusion that with practice I could eventually get comfortable on a 450, but maybe not comfortable enough to make the necessary push in a race...especially when, looking at my upcoming year, I'll probably only make it to 2 rounds next season. Just not enough seat time.

(And yes, I know other 600 chassis are less aggressive than the R6, but it's all of a breed).

Most people considering these bikes should absolutely go for it.

So I came excruciatingly close to pulling the trigger on this nearly complete SV650 project. (And by the way, somebody should buy that -- that's crazy gear for the price and I've ridden with the seller, he's a solid guy). But man, the SV grids in AFM are pretty feeble this season! Last season they were good, so maybe they'll come back?

Who knows, but I made the difficult decision to follow a different (and probably ridiculous) path -- I'll be building up my ghetto sumo into a light-bore track RACE tool, then try and hunt me down some Ninja 300s.

That dumbass idea will be chronicled in a build thread to be started soon. But as for my original 450 vs. SV question? Any aspiring AFMer would be stupid not to go with the 450. And if you're a So Cal rider, where the SV grids are still strong, you'd be stupid not to snatch up LA Law's bike for sale.

Me, I'm just stupid.

Thanks, everyone.

^ Geez, with your handle I thought maybe for a second you were King Kwong and was glad I wasn't gonna have to race against your again!

You mean first racing round ever? Do it! Your life will never be quite the same. And the SV is a fun as hell way to go racing.

No problem Noah, it was fun, despite my meatball antics.

Get a bike, any bike, and get going. If you're like me, bikes come and go. Also, somebody will pass you at a trackday, your brain will flip a switch and you'll be back racing in no time!

Charles

Thanks again, Charles! I definitely know that switch. It's amazing how much faster one can go when properly motivated.

I remember way back when I did my New Racer School for WSMC we asked the instructor (former pro Jason Curtis) at the end of class what we could expect to happen in our first race. He said, "Well...you'll go 4 seconds faster around this track than you ever have before." We thought he was full of shit. But that's exactly what happened.

A green flag and a competitor do weird things to one's mind.

I may have been unclear in my pronouncement for the future...I'll definitely be showing up to race. Just looks like in 250 Superbike or something.

Just swapped the gears and crippled a cylinder in my R6 this weekend (Thanks MZarra!).

Gonna give this 450 Cripple a try and get out of the meat grinder they call the 600 classes
