Malossi MHR Rep or Polini Alum Racing LC

Just purchased a 2003 Derbi GP1 50 LC for myself for Father’s Day lol. I’ve got a Yasuni C16 for it that just came, which kit do you think would be best for that pipe?

I’ve heard Polini makes a higher quality kit. And just run a short intake or I have a Stage6 MKll intake steam I could run too on it?

 

I used to run an MHR-rep with a yasuni C16 and a 21mm carb ... and it was a very good combo.

The scooter was plenty quick, a whole world quicker than the polini sport cast iron i ran before it.

im afraid i have no experiance of the polini kit you linked, so cant really pass judgement on that.

The Corsa and the MHR-rep are pretty similar out of the box performance wise, although the MHR-rep being aluminium has better thermal abilities.

 

you must be stateside then is you have an SSS ported cylinder ? if so as long as you can afford it I would get SSS to build you engine for you , think they charge around $150 to do it + parts , and the MHR -rep is lighter and has better cooling , check out SSS YouTube channel , one of the best.
