Not much available performance wise for the Reflex except for a big bore kit which brings the 249cc up to something near 270cc. (pretty much what the NSS300 Forza is now displacement wise) And a taller final drive gear set that usually gets installed with the BB kit. However, I have only heard of a couple US riders doing it and both ended up with toasted engines. Maybe they did something wrong or maybe the European version (that's where the kit comes from) of the Reflex NSS250(Jazz) has slightly different specs?.....who knows? Some have twiddled with jetting and different exhaust pipes with sound that was more pleasing to them but HP was not significantly increased. (though fuel consumption was!) The caveat here is that the catalytic converter is built into the standard muffler. I don't know of ANY after market mufflers that would be EPA compliant. Removing smog related equipment from vehicles is a no no as far as the EPA sees it. It may seem to be a low risk change, but you might run into trouble if discovered.

I have the taller Polini final drive gear set on one of my 4 Reflex scoots along with a taller tire so for given speeds, the RPMs will be lower. (lower RPMs means less fuel being used) This modification is being used in conjunction with a streamlined fairing I am building for my 2007 Reflex. (not done with it yet, but in the process.) Did a 200 mile test ride on the bike before stripping off the tupperware but was not impressed with the results. Maybe with the fairing it will be different. (better economy)

The taller tire has a bit of controversy because it is a car tire. I originated the use of a car tire on the Reflex way back in early June 2008. Successfully I might add, and several others have done the "Darkside" thing to their Reflex scooters as well since then. It seems it is not for everybody, but it is a viable option that has its benefits.

There are some that do mods to the variator by swapping out the moveable drive face of the variator with one from a Big Ruckus, removing just some of the rollers, using rollers of different weight than stock or using DR Pulley slider weights or a combination of these mods. Some have even experimented with Malossi variators and clutches with varying degrees of success.

With 4 Reflex scooters, 2001, 2004, 2006 and a 2007 you might say I'm familiar with the Reflex. A service manual helps with that.

And welcome to the forum.
