You can do slipons and air cleaner if you use the SE tuner. The M8 runs strong out of the box but does need some sound in my opinion

 

 

The cool flow fan will help with heat in slow moving traffic.

 

Appling the "Warranty" rules vary by dealer. Some are strict and some overlook mods, especially if they did the mods.
Having said that, most, if not all warrantees state/mean:
Any mod or any accessory not manufacture approved and not made/added by an authorized dealer will void the vehicle warranty.
Now does adding as set of after market grips void warranty, if the motor "breaks"? Of course not. But if one adds even a set of after market slip ons and you say, burn a valve. That could, depending on the dealer, results in a warranty coverage refusal.

 

just get the SE Stage 1, it'll process more air thru the engine producing a little more power, sound better and warranty won't be compromised..and the cool flow fan and mid frame deflector should displace excessive heat..fwiw..I heard the new Street Canons on a bike last week and they sound great, better tone than their predecessors which I have and like, but if they ever need to be replaced I'll certainly go with the new ones

 

Try it stock. You may really like it as we do ours!

I've done mufflers, pipes, tuners, breathers, you name it on three previous bikes. All cool and I like most of the modes. But at 60 now the wife and I just really like to ride. Our 2017 CVO Limited with the 114 has crazy power (to me). Even the wife feels the difference as a passenger.

I put my money in new bars and Pro-Action rear shocks and have a sweet ride.

 

not bad advice either..as much as we ride there's plenty of money spent on comfort mods, tires, service/maintenance, fuel, hotels, food and drink you name it. performance increase it pretty low on the list list of needs/necessities

 

Yea, I would test drive this first. This bike stock puts out 122 ft lbs of tq, which is the same as my RKS with a stage III kit, so you might not need any performance upgrades!

 

People are always gonna want more, coming off my full stage 1 107M8 to a 2019 117M8 and to be honest, it's really not a huge difference. All the dyno runs I've seen for the stock 117 is 93hp and 112tq, so basically a 107M8 with a good aftermarket cam puts out better numbers. I'm perfectly fine with it cause it's a big heavy tank so I wasn't expecting a drag bike, it does just fine for what it is but the power junkies won't be satisfied with it.
