Success in changing tires/brakes/suspension?

I love my TC and honestly couldn't justify buying a motorcycle since this outperforms most 125s/150s in traffic easily. My current problem is with the brakes/tire grip.

I'm interested in switching the tires to see if I can get more grip/stability, but not sure where to start or how to identify a better tire.

Same thing with the brakes. I'm not sure how to check what would be better in the aftermarket. Anyone have any ideas?

With strong enough winds going top speed the bike has wobbles which i'd like to get rid of if possible. My second battery will be paralleled next week so I'm hoping the extra weight will help a little bit, but think there's more to be done.

The last problem is the suspension. I feel like i'm getting ass blasted over any significant bump in the road. Especially at 50-70. Anyone adjusted theirs with any success or maybe changed the shocks?

Anyone with any success for any of these problems?

Do you think you got more benefit from changing the tires or changing the handle bars? Do you also have the wind instability at high speeds? It feels like i'll slip so I end up slowing down sometimes.

I recommend changing the tires. I have Michelin Pilot Street. The bike is faster with them (32 km/h -> 36 km/h on my mountain road), it feels safer in curves, no slippage on wet roads. The ~120 € were worth the money.

The original aluminium handle bars are too soft and with the slightest hit they become deformed. They are next on my list. And the rims break easily. Anyone with a recommendation of a compatible front rim?

Yea mine isn't restricted so i'm doing ~70. I really feel the difference in road conditions. If i'm driving on pristine road there's no problems, but top speeds on roads that are bumpy or have some ruts is rough. What size pilots did you get? I'm not sure about the exact sizing of the tires and what would fit.

Maybe this is a bit of dead topic now, but I've been thinking some of this instability comes from the relatively high center of gravity on the bike? To me it seems like with the battery and such, with the way it sits, it's up over top of the 'pivot' of where you lean on the bike. A typical motorcycle has it's engine low in the frame, between the wheels, even faster e-moto builds I've seen seem to have the battery lower, center of gravity closer to being between the wheels.

@sdreaver not at all on stock tires I was able to lean quiet far 40 - 50 degrees. It feels ok, like normal bike. It's little "lazy" in the corners in some speeds but this is nothing extreme.

The Michelin tires have the same dimensions as the original Cordial ones. On my TC: Front 90/80 – 17", Rear 110/70 – 17". My GPS measured top speed without wind on even road is 63 km/h (72 km/h on display). The motor shuts down above 65 km/h (GPS), so even downhill you never reach more than 71 km/h GPS (81 km/h on display). The speed increase of the Michelins is most notable going uphill. They make a certain humming sound due to their profile. The Cordials have poor performance on wet or dirty roads, on dry roads they are ok.

I wonder if we have different models or firmware or something. Downhills or with a bit of wind I easily surpass 70 on gps. Thanks for the measurements. The performance in water in abysmal with the stock tires so if there's an improvement there it'll be worth the big cost to change them.

Have you changed the brakes? I can't stand the tsch tsch tsch tsch sound of the discs turning when driving slower speeds, not to mention the squeals when you apply the actual brakes.

Hi.

I'm happy with the Pirelli Angel CT tyres in stock dimensions, they do need some kms on them to scrub them in.

As for the brake noise, that is due to your disc not running true.

Best you can do is take the caliper off, clean it thoroughly and lubricate the pins and the back of the pads with brake grease.

That should allow more free movement and cancel out the squeal and rotating noise. If it doesn't work, buy a new, true disc or a pair of earplugs 😉

I hit max... Shinko 705 120/90 front 130/80 rear - this is the final frontier. You physical cannot put larger tires without changing swing-arm and forks. As a bonus... speedo is showing almost correct speed +- 1km

@m66 This is great news. I got 130/70 for the rear and am planning on 110/70 for the front (since that's what comes in the tires I wanted. The Pirelli Diablo Rosso II) and now I know they'll for sure fit without issues. Got a really good sale on the one so I couldn't pass it up and just sitting a bit until ordering the next. 

Did you remount the rear fender somewhere higher?

@sdreaver There are few catches - forgot about rear fender. There is no way you can keep it. It sits to low. In my case I will be changing shock for one that is  longer by 40mm - 280mm total because I want to have that stubby scrambler styled fender. Also you need custom or additional locking plates, as you need to move wheel back and current locking plates are having only 1 position. I made my own from old motorbike chain tensioner. In near future I will have custom made locking plates. Old ones are now doing job of locking washers.

@sdreaver I missed 130/70 - with this tire you will probably keep the fender full or modified one. Stull you will need custom locking plates.
