5 of 5 Excellent plug and play cylinder with strong resul Saturday, January 31, 2026
taco eater : Juls_Italy from Jacksonville, FL United States  
I am running this DR 43mm kit on a 2003 Kinetic TFR with the following setup: intake opened to 12.7 mm with a 13.13 carb, Malossi air filter, Mazzuchelli Anticipato crankshaft, and stock TFR head with decompression valve.

I chose this cylinder over other options based on bench test results performed with unmatched cases (Video on youtube, not mine. MIGLIOR KIT 43 PLUG AND PLAY)

Malossi CVF: 3.4 CV / 4.8 Nm
DR EVO: 3.2 CV / 4.5 Nm
Olympia: 3.1 CV / 4.5 Nm
Polini: 3.0 CV / 4.2 Nm
Polini Racing: 2.7 CV / 3.9 Nm

Only Polishing the Exhaust Port

5 of 5 banger Monday, May 8, 2017
taco eater : Will C from san francisco, CA United States  
all the dutch vespa guys run these for a reason. it's pretty much the best overall. great torque and low rpm performance + revs out seemingly forever

warning, the exhaust flange is a bit fragile due to the ID being quite large. be careful and it will be fine. give it a good smack on a curb and it will break off.

that being said, this kit + 43mm polini head, gianelli MEGA pipe, 13 sha, drilled out intake, maxed out rotary pad, mazzi anticipato crank, 80 pulley and malossi shoes gets me to 48.6 REAL fast

5 of 5 This is a beast Wednesday, April 23, 2014

I love this kit, bang for the buck.  I broke the exhaust port, that sucked, but got it welded back on at a machine shop for $10 and now this thing works again.  Also tried the Olympia kit and this one is much better. Cast iron does suck i wish the quality would be like the original but im still happy with it.

Awesome kit. Port edges were p-sharp, quick hit with some rotary jewelry stones and they were nice and beveled.

Don't skimp on the prep... gonna add oiling holes to the piston next time I'm in there...

Rad kit for sure. Super hi rpm, super fun.

5 of 5 awesome Monday, June 10, 2013
taco eater : simon from chicago  
casting quality is pretty good, still probably a good idea to clean up your ports a little. but once you do that, it's a trouble free install of a great kit.  (don't listen to the guy who says you have to jb weld the cases - that will only happen if you mess up the case matching.) haven't had a chance to gps it yet, but with a 12.12, proma circuit and notched stock variator, it easily pegged the 40 mph speedo on the bike and had more to give. if you're running a stock variator with this kit, notching/windowing will allow you to utilize more of the kit's potential.

UPDATE: zac must have gotten a bad one because mine doesn't have any issues. runs cool and i have done miles and miles of WOT at a couple of rallies with no overheating problems.  blasting past the k-star puchs with this, proma circuit, polini vario, cut crank and fast stock gears.

Way better upgrade than buyin a pipe and cheaper if you're on a budget. You should rebuild your motor anyway don't be skurrrd
