Cool GPZ550/675 Racer

and a winner too!

During my gpz data gathering, came across this.

ridden by Andrew Mauk / Team Momba to the 2009 AHRMA Vintage superbike middleweight championship with 8 straight wins.

Been told is sports a 675 kit, close to the 685cc class limit.

Does anybody know more/have better pics?

Looks like a lovely ride....

There are several write-ups about this bike/team in one or more magazines...if no one posts, I'll dig through my mountain of mags to see if I can locate the article(s).

she does look like a nice ride, I like the bike too

I did find some material about their first effort with a swap meet based 550LTD back in 2006 (i think), that one was covered indeed by "motorcyclist classic" mag.

couldnt find anything about the newer gpz based project that took the championship last year though.

Maybe that is what I'm remembering...but I'll still look tonight.

Does any of those Momba guys hang around here?

It is actually 676.... check mjg's link

Excellent info there MJ, a pity that all ht epics link are not valid anymore

Thanks a lot!

615 is the typical Wiseco kit. Momba II went beyond that.

Indeed, the post in gpz550.com mentions that they wanted to make the 676 kit available for sale. Wonder if they managed to bring it to porduction, that post is from 2 yrs ago.

A 80 hp "550" sounds super yummy.

for the time being i'll stick to my gpz750 racer build, but such a 550 is tempting too.

From what I remember, they had some reliability issues with the 676. I'm at gpz550.com quite a bit and the story was big a couple years ago. Corey Clough has been keeping in touch with them so maybe he can chime in.
