Suggestion for the 2018 Rulebook

[tecknojoe]

2.4.1 section 3 - Supertwins GTU

Modify Supertwins GTU to match the Moto America Pro Twins class.
Up to 850cc twin (excluding the 848)
Weight restrictions for 800cc and above

If we choose to modify only one class, STGTU makes more sense than LWGP because whatever bike you race in the Pro Twins ruleset will also be good for Thunderbike and STGTO, both on Sunday.

Respectfully, I disagree that Supertwins GTU needs modification. This is precisely what the Thunderbike championship is for. Smaller than Supertwins GTO, bigger than Supertwins GTU.

Personally I am about 100 days away from having everything done for 2018 (all parts in and all vendors ready to go), and guessing others are in the same boat. Our whole program is built around 700 cc's, to change this soon before 2018 could cause a major drop off in attendance in an already small class. At a minimum any consideration of this should be for 2019.

Further, there are 10 different classes you can run a 600cc bike in, but really only 2 you can run a 700cc bike in and be competitive to win. Now we are going to get rid of one of those two classes? I think Thunderbike is perfect for those AMA legal twins to earn a championship. Chris Fillmore didn't have any trouble running his twin in RORO. Increasing the size of Supertwins GTU puts that and Thunderbike too close together in classes we already struggle to fill.

I suggested STGTU because the Ducati 749s won it last year - ~110hp. Pro Twins bikes will still struggle to reach that level of performance, but will be close.

LWGP could be a different candidate, because the pro twins rules are aimed at people building up their SV, FZ, 650, etc. Like Tony's bike.

The 675 and 848 in thunderbike are a higher level of performance than any pro twins bike will be.


edit - suggest weight limit for 750cc and above, not 800cc and above
