Thanks for the positive feedback. First priority is to get the new project into production and after that we will be concentrating efforts on performance upgrades. We sponsor a national team running MSX125s (Groms) in the Thai Championship (partly owned by the SAG Moto2 team we sponsor too) and the power these bikes get compared to stock is the difference between night and day. Reliability is key and we'll be doing lots of dyno and track testing before launch of any new performance products.
On the exhaust, good idea about the back to back comparison for noise. The quieter version will work out a little cheaper too (around 50 dollars) than our existing carbon type so that is an added bonus.
BTW, nothing on our kit will be B grade. Our GRP products use only the best imported European epoxy resin (approx 3 times the price and strength as any polyester on the market and the same as used on OE Ducati carbon etc.) It is is tough and very flexible. The down side apart from cost is it is harder to work with and takes longer to cure than polyester so most people avoid it. However, the end product is worth the extra effort. We will also be making a complete kit in carbon. It will obviously be more expensive than the GRP version but on the plus side, carbon is even stronger, lighter and sexier, so as usual, we will try to give owners as much choice as possible.
