MotoAmerica: Proposed Technical Rules Changes For 2019

The twins class is going to be even better in 19

MotoAmerica: Proposed Technical Rules Changes For 2019 Released

AMA/FIM Technical Regulations for MotoAmerica

Proposed Rule Changes for 2019

2.3 General

2.3.7.1 Junior Cup tire allocation

2.4 Superbike

2.4.10.1 /e./ii. and f. Newly homologated machines (homologated after 2018) will not be allowed to make frame modifications to the steering head or swing arm pivot area. This does not effect currently homologated machines.


2.5 Supersport

1. No changes


2.6 Stock 1000

2.6.10.4 Swing Arm

f. The sides of the swing-arm may be protected by a thin vinyl cover only; no composite or structural covers are allowed.

2.6.10.7 Brakes

e. Front master cylinder may be replaced. Price capped.


2.8 Twins Cup

Once a motorcycle has been homologated, it may be used for racing in the corresponding class for a maximum period of twenty (20) years or until such time that the homologated motorcycle is disqualified by new rules or changes in the technical specifications of the corresponding class.

2.8.2 The following engine configurations comprise the Twins Cup class.

Over 600cc up to TBA 10/1/18 4 stroke 2-cylinder water cooled

Over 600cc up to 800cc 4 stroke 2-cylinder air cooled

2.8.4.1 The minimum weight will be:

All machines 135 kg (297.6 lbs.)

2.8.8.5 Cylinders

a. Cylinders may be bored to a maximum of 2 mm over standard bore or up to a maximum total displacement of 700cc, whichever is less. Machines with a standard displacement greater than 700cc must remain as homologated.

2.8.8.11 Crankcase /Gearbox housing

b. Internal bolt on brackets and/or bracing may be added to the crankcase to increase strength however welding on the crankcase is not allowed.

2.8.10.1 Frame body and sub-frames

j. The front and rear sub frame may be changed, altered or removed. If the rear sub frame is integral to the main frame, additional seat brackets may be added and non-stressed protruding brackets may be removed if they do not affect the safety of the construction or assembly. Rear sub frames that are integral to the main frame may be removed and replaced with a detachable sub-frame. Bolt-on accessories to the rear sub-frame may be removed.


2.9 Junior Cup

2.9.3 Balancing various motorcycle concepts

The MotoAmerica/FIM Commission reserve the right to apply balancing to the machines in the class as they see fit in order to maintain equality amongst machines. Methods may include but are not limited to the following:

- rev limit

- weight limit changes

- restrictor plates/ throttle stops

- engine and fuel injection power up kits

The decision to apply the handicap will be taken by the MotoAmerica/Superbike Commission at any time deemed necessary to ensure fair competition.

Stupid people say stupid things on the internet, so be wary of who those people are. If you solicit advice on the internet, just keep in mind 99% of what you'll receive is not based on fact or science-and likely atleast 95% of it is based on bullshit and bravado regurgitated from some other schlub who also did not experience any of what they claim and are also full of shit. If you don't like my bluntness- too bad. I am not here to please you, so move along, your approval is not desired nor is it needed. So before opening your pie hole and adding more stupidity, perhaps sit back, listen, absorb and learn something. You know that saying, it is better to remain silent and thought a fool than to open your mouth and remove all doubt!

That was a 796, that they used just to scope things out with. They would run the 797 though if it gets homologated. Then it would have fairings and stuff too. Renzo was pretty slow on the Monster in the dry. During the CCS weekend the week before he was running only 1:34s while top guys were doing 1:30-1:31s. I think in MA practice he got down to 1:32s, but that was still over 3 seconds off pole position. Funny thing is Renzo has ran 32s on his ninja 400 there lol

Seems like the twins cup was designed as a run what you brung type of class but now it appears to really be a tuner class and if you’re a regular privateer without a crazy built 650 you’re now screwed. R.I.P.

700cc overbored ninja 650 with all supporting engine work is gonna make like 100 HP lmao

The twins class was always meant to be a tuner class.

MOTOAMERICA TWINS CLASS EXPLAINED, PART I

The class will play host to several 600cc to 800cc twin-cylinder bikes, with a rule package designed to allow freedom to builders and small shops to make their own modifications and custom builds. Engines can be extensively modified, as can some of the chassis components, and an open-ECU rule will make for a tuner’s dream. Low minimum weight limits add to that — also being the reason for strong power-to-weight ratios and undoubtedly quick lap times.

Check out this SV 650 for the IOMTT with prototype chassis/ swingarm and fork conversion. . 90+ whp.

^True. From when they released the rules initially about this class it was pretty clear it was gonna be a "who's got the deepest pockets" type of class. However, I'm happy to see that's not been the case this year with Madama and Parrish fighting for the championship going down to the last race. I don't know much about Parrish but I don't think either of them are rich guys that threw tens of thousands of dollars at their bikes. Madama has ridden 2 different bikes this year as far as I know. One is his own FZ07 and the other one is an AP built FZ. That one is faster of course but I think he only did like 2 rounds on that one, most were on his own bike.

If you have an SV and don't have a GSXR front end on it, it's not a good SV lol...also might be illegal for some classes, probably even MA Twins.

I knew a guy who had an SV with a GSXR front end, plus a bunch of engine work done. It was basically a $20k+ SV650. He would race it in CCS many years ago even in classes that it wasn't legal for. After he'd win or get a podium or something, he'd come right back in to his pit area, and put the bike in the trailer and close the ramp cuz other people would come looking for him to bitch about it but nobody could ever find him lol

Madama has been on an APmoto bike all season, even when Altus Motorsports was all over the bike (former employer of APMoto).... Altus pulled out right before Pittsburg, leaving Madama to ride on of the local trackday riders bike (MN guy) with all the AP ram air, custom exhuast and engine build (big cams, big ports, "stock bore"- possibly really the 3mm overbore kit, bored throttle bodies, slipper clutch etc....)......... but that bike was actually owned by Jenspeed, Ward or Paul Jensen (brothers).......... it was simply a "loaner" bike so he could compete that round

And FYI......... the APmoto FZ07 engine and tuning packages are tens of thousands of dollars, AP does assembly- but all machine work and parts are outsourced
I know, I work on 3 of them......... And AP is only a scant 90 miles away and has been working out of Alden MN all summer

he spends gobs of hours on the MotoAmerica bike(s), but leaves everyone else hanging is the grim reality


R6 front forks, aftermarket offset triples, R6 wheels etc all on the FZ07R......... all legal per the rules--so surely gsxr forks and triples on an SV is legal
