Hi folks, I've noticed the back tire on my 2012 GTS 300 is worn down and should be changed out as soon as possible. This is my daily ride to work.

It's also on (as far as I know) the original brakes. Bike is nearing 19,000 miles. I'm going to ask the dealer to flush the brake fluid when they change the pads.

Is there any other maintenance I should consider while they have the rear wheel off?

It might be due for coolant change, too. If it's the original battery, that may be running on borrowed time. You might have the battery tested while the scooter's in the shop.

I just replaced my rear tire yesterday (Heidenau K61, I got about 5500 miles from it). The local shop told me its $90 for them to remove and install the wheel and free if I did it myself. I'd never done it before. I watched McBergsma's youtube video. It was pretty easy. I didn't remove the body panels like he did. Took about 20 minutes including having to torch one of the wheel bolts because I couldn't loosen it with my impact driver. Once heated, it came out pretty easy.

Shop charged me $20 to replace tire and balance the wheel.

I'll remount the wheel today. Note that most of the bolts have torque specs that McBergsma give in another video (or you can look up yourself). I'll also have a look at the pads and measure the brake rotors and pads as well before reinstalling the wheel.

BTW, I bought a Heidenau K80 130/70-12 tire. The K61 is not available any longer and the shop thought the K80 was a better tire. Tires seem to be the most expensive maintenance item by far: ~$90 for rear tire incl tax. All the other maintenance parts are cheap by comparison.

Has a new battery, but fresh coolant probably wouldn't hurt.

Are there any sort of bushings or anything that should be inspected/replaced while the rear wheel is off?

I don't know what the part is called but the frame that the axle goes through has a bearing and you should make sure the bearing rotates smoothly. Its the black part that Mitch is installing here:

While the wheel is off it is a good time to change the fluid in the rear hub.

Not necessary yet, but it's quick and clean when the wheel is off.

What's your verdict on the Heidenaus?

My last CG2 only got 4000 miles before hitting the wear bars, so now I'm overthinking its replacement. From the research I've done so far, it seems that Pirelli scooter tires are less comfortable on rough pavement and may have a short life compared to the City Grip 2. Haven't found much about Heidenau.

I'll probably just do the convenient thing and get the CG2 that's in-stock and matches the front, but now I'm wondering if the grass is greener on other rubber.

Do you use this same process to decide what bread to buy? It's a tire. Buy one, stick it on your bike and see if you like it.

I know you weren’t asking me, but I have opinions.

For a while, back in the late aughts or so, it was fashionable to run Heidenau K61 tires on the GTS -- especially a 140 on the rear, which is pretty fat. It was a nice tire with a great lifespan.

I ran them for a while, and I seemed to like them less and less with each new tire. My final conclusion, at the time, was that they made the GTS feel “dive-y”, which is a bit hard to explain. In a hard turn, there was a point at which the steady progression of using more and more of the side of the tire would suddenly change, or at least would become somewhat less predictable. The speculation among those of us using them at the time was that the very stiff sidewall was largely responsible for this weird feeling, though that was really just our guess. Some riders didn’t mind this effect, but I really disliked it, and stopped using the K61 because of it.

I don’t know if they still feel that way, as I haven’t used one in nigh on a decade or so.

It’s slightly more of a commitment than buying a loaf of bread. If I don’t like the bread, I can just throw it away. Changing a rear tire is a bit more involved.

Also, tone down the snark. This isn’t Twitter. Thanks.

Thanks Jess, that's really helpful!

I guess I'll just go with a CG2 again and hope I have better luck with this one.

this may come as a shock, but every manufacturer makes good tires. I mean, if they didn't they'd be out of business.

Pirelli has several options. of late the angels seem to be in favor. the SL26 is very decent
Michelin the same. city two seems to be favored lately, but the power pure is a great donut.
duro, hard as rocks
shinko, bargain basement but okay. just no whitewalls.
Metz & IRC are $$ but if you're looking for longevity and decent handling
Heidi's are great, kinda middle ground spendy but do everything well.
kenda, I'd put above shinko. affordable decent replacement commuter tire.
Vee, been around forever but I don't have any first hand knowledge on.

Soft Brembo's last less but ruin the discs less while maintaining better braking.

there are many options that provide superior braking performance, longevity and are easy on the rotor while meeting a much lower price point.

brembo makes great calipers. their pads are outsourced horseshit. or, at best re-bagged OEM from the suppliers.
