Cripple Triple

I'm very interested purchasing or modding a 600 into a cripple triple. Been reading a lot more from http://www.450triple.com/. The modifications seems simple enough. Would be awesome to run around with a 80 HP bike that's has really good OEM suspension and braking components.

For those that race or track these bikes, what is it like? Reliable? Should I buy or build? Also, do I need to really dyno the bike once the cylinder is disabled?

Any ownership insight would be greatly appreciated.

First of all, it's a blast.
If you do the injector mod it shouldn't take more than half an hour once you have the parts as long as you're familiar with working on bikes. The r6 requires you to do a little bit of wiring to modify the harness.
As far as what it's like, it was frustrating at first. There was definitely an adjustment period because I had already ridden my bike at full power for a season when I decided to cripple it. It made it feel a lot like riding my SV but with no torque haha. It's a lot of fun to ride, but like any low power bike it requires you to work a lot harder, and if you do make a mistake, you don't have the power to just make up for it.

If you can find a bike that's already crippled that's great, but I wouldn't hesitate to get a non crippled 600 that's already track worthy and just disable it yourself.

I took mine to the dyno, and it barely changed anything, however my friends gsxr that we did at the same time ran terribly as a 450 and having it dynod made a big difference.

Find a 600 and go for it. dont know of any 450 triples for sale at the moment. Dave Moss many have an R4.5. you can get all the help needed. we have no secrets and everyone in the class is willing to help. having a fuel map done is recommended. dyno tune or get the Woolich log box. depends on what you plan to do with it. there are a few 450s that can be switched back to a 600 in a few minutes and can race in both classes.

OMG I LOVE my Triple!!! The bikes are soooo much fun to ride... and the 450 Racers are an awesome group of people!!
Can't wait to get back out on mine later this year... looking like Sonoma at this point.
You will NOT be disappointed! :thumbup

Best way to get into racing in my opinion. I bought one of Dave Moss's old bikes, but buying a 600 track bike and crippling it seems like a fairly simple process.

I have had no issues with mine, so reliable? Yeah, sure.

Again, I got mine pretty much ready to race, but I have heard time and time again that tuning after crippling is absolutley nessecary.

Lastly, the 450 cripple crowd is a great bunch of people to race with!

Echoing what others have to say and adding some more:

Buy or build? the "build" is so easy now that it doesn't matter. As you read, there are several ways of crippling the bike. some require pulling the head, but others do not. If you are doing the injector bypass method (most popular now), then it's 10 minutes max. If you are doing the cam grind method, you have to pull and grind the cams: a couple hours at least. If you want to pull the valves, then the head has to come off, I would think the better part of a day.

Dyno? definitely recommended, though I would say this for any racebike, especially if you have made modifications.

Reliable? just as much as the base bike. We haven't seen any mod related problems. The only issue I've had was that I used the wrong tubing for my injector bypass loops and they melted. Don't do that.

Ride? Lower toque, more engine braking, modern suspension. My bike feels very light to me and drops in to corners very easily. The racing action is great though, I rarely have a lonely race anymore. There are usually others to dice it up with.

Support: We're all willing to help, you just have to ask.

If you are doing the cam grind method, you have to pull and grind the cams: a couple hours at least.

Or you can save your original camshafts and get an identical used set (Ebay, etc.) to modify. When/if you decide to revert reinstall your original cams. :eboy

True. This was one of the original "pros" of crippling: you can easily return it to a 600 in case you fear a loss of value. Though now maybe they have equivalent/higher value.

I'd say buy if you can so that someone else has already paid for suspension upgrades. Otherwise build it. Racing a lower Hp bike will make you a better racer, IMO anyway.

is there any development on just flashing the ecu and physically not touching any other part of the bike yet to bring it from 600-450?

I'd think that would be a big no no for racing as someone could easily switch their map during the race.

For the gsxr's with the Woolich kit we have been able to turn off the injectors for one cylinder. So, yes, you can just flash the ecu to make a triple. For racing with AFM, they require some sort of physical change to be made that requires tool to switch back and forth.

The simple solution is to get 2 extra injectors (one for upper, one for lower) with the loop of tubing, pick a cylinder, then unplug the connector from the injectors in the fuel rail and plug into the looped injectors. Done.
For optimal performance in 600 and 450 modes you'll want a custom map, too.

I woke up today to the same idea of crippling my R6 to run the bike as a 450 in OMRRA.
I get to race more classes this way.
I was reading up on the different ways and looks like this one is the quickest way.

"The simple solution is to get 2 extra injectors (one for upper, one for lower) with the loop of tubing, pick a cylinder, then unplug the connector from the injectors in the fuel rail and plug into the looped injectors. Done." Is it the same thing mentioned in the link above?

thank you for clarifying, ive been asking since last year since I met a guy @ a trackday saying the development of the ecu flash - is here and is currently being used (600-450 ecu flash)

then i asked dave moss about it and he was not familiar with that method, now i see what the issue is at hand!

found this thread looking for something else.
There seems to be a mistake in that running as a 450 with ONLY the injectors bypassed is AFM legal; it is not. You still have to have a mechanical disablement to the engine.

How else could that be accomplished without pulling the head to grind cams or remove valves?

I think the rule book just states that some physical modification must be made, and then they list the injector bypass as an example of that. I figured that the phrase physical modification was meant to stop the purely electrical methods mentioned above, not meaning something mechanical has to be done internally.

The listing of injectors in the parenthesis was, as I understand it, meant to institute an allowance for an electronic only conversion. However, it seems tech was not consulted and has held, the entire time, that a mechanic disablement was required.
There are only three methods that I am aware of that satisfy this, and only two are specifically approved.
One way, the original way, is to remove valves.
The second way, is to grind off cam lobes.
The third way, which I had permission to do experimentally, was to remove a spark plug and to put a solid plug into the hole. (All require disconnection of fuel). I would get permission from tech before trying this.
