Suitable tyres for a CB125t?

[motorbyclist]

Long story short, I don't trust the old tyres that came on the bucket... Any recommendations (or offers?) on cheap and suitable tyres?

rims are stock at 18x1.40 front and 18x1.60 rear....

[MSTRS]

Cheap? Or trustworthy?
Doubt you'll find both wrapped up in one...

sorry, I mean affordable... I'm not looking to dick around with slicks or anything silly like that..

I see there's a sale at cycletreads on BT45

[quallman1234]

For the price of Buying decent 18 Inch tyres it is almost worth it to just swap to 17's and buy some slicks. You can't get anything anywhere near close to slicks in 18's.

But you probably already knew that!

[motorbyclist]

are slicks really worth it for these bikes? I mean, it was dyno'd at 15.5rwhp over 12 months ago by the owner before last, but I can guarantee it isn't back up to that.... yet....

[Muzzab]

Can you get BT39's, I'm happy with them on my bucket.
I run BT45's on my Pre82 GSX400 and on my road bike and they seem OK to me.

A 17" conversion seems the way to go, if you are prepared to pay as much for wheels and tryes that you paid for the whole bike (in my case anyway)

Oh, good.
BT45s are great tyres. So are Pirelli Sport Demons. Dunlop GPRs might come in 18" or TT900s if you can find them.

The moment you try slicks you will know the answer.

They are definitely worth it. And with practice you change both tyres in round 40 mins or be lazy like me and buy a second set of rims.

ITs not the size of your horsepower that matters its the way you push that horsepower while enjoying it.

I find lying down next to the bike when cornering helps.

Until you fall asleep that is.

A popular upper mid field A grade rider that I know of at Mt Welly has 14 rwhp last time I saw his FXR on the dyno and the hot boys at the front are peddling 16-17 rwhp.

Slicks or Sports tyres, it all depends on the cornering speed your looking for, at Mt Welly its very easy to try and corner harder than sports tyres will allow.

[quallman1234]

Slicks are the way. Power espically at Mt Wellington, is second to handling.
Slicks tend to soak up alot of the poor suspension/chassis.

[Henk]

Agreed, at Mt Welly handling and corner speed largely trump power.
At Kaitoke, maybe not so much.

Road tires will cause you more pain. Grab a handful of front break and you will soon find the reason everyone likes slicks. The difference between a face plant and stopping.

[Squiggles]

How many have run road tires on 17's before changing to slicks?

[Trudes]

How many have run road tires on 17's before changing to slicks?

I did.... but I don't ride very fast so probably not the best person to make comment, however I do prefer the slicks, they have given me a bit more confidence and the rear end doesn't slide out as much because my suspension is all fucked up. I ride in the wet on slicks too and only find them dodgy when you hit wet paint (I avoid the big puddles if I can). Getting second-hand slicks that have only been half worn has been a breeze so far too. I'd never go back to road tyres.

[richban]

Yep ran brand new tt900s they were shit in comparison. Slicks are on another level all together in the wet and the dry.

Dito..........

[Henk]

Ran BT45ss's slicks are better.

[koba]

They are better in the wet than road tyres too...

[motorbyclist]

Right, so how much time, money and effort is a new set of wheels and/or second hand slicks going to cost? It's my first time bucketing and the bike only cost me $350 plus maybe another $100 in bits and a couple of afternoons to get her running again!


Is there any road tyre that is markedly better than the others to fit the stock 18" rims on a cb125t? Even if I go to slicks later I'm really just trying to get something to start on for the next bucket day and see how it goes...

[Henk]

Probably the best road tyres you are going to find will be the BT45ss yes the ss is part of the part number. They will cost though, wheel conversion is probably a better bet in the long run but will not be as easy as bolting them in.

Just race it on whatever, cheapo yung feng pong tang tyres, the fucked old ones it came with, anything that will hold air is good for a start.

It's all still good fun.

What he said. First time out I went with the old shitters on the bike and had a ball, mind you it was raining, and I did crash a lot.

Yes and we all know who to see if we want our bike crash-tested. Hmm, you're up for some of that soon. Then again, a couple of newbies are pretty good at it too (funny, rain happened with them as well).

Back to the topic on hand, ride your bike how it stands, see how it goes. Come to a meeting, talk to those running CB125T's in person, look at their bikes, and take it from there.

[F5 Dave]

Indeed, come race, but look at JCs 125Ts & the wheel conversions done & go out & buy some 17" wheels. Yes it will be some money, but if yer careful not too much & they could always be sold on as 17" in right size rims are valuable. You want 17x 2.5 front & 17x 3, or ideally 3.5 rear. The disc will be the most expensive item. Wheels might be as cheap as $250 if yer lucky. Maybe another 100 to get a disc (can use straight but under WOF thin) & sort out some spacers & sprocket mount.

I mean yer not talking too much money & slicks come by for ~ $70ea, sometimes less.

I got a pair of FZR/TZR 250 wheels for $100 off trademe, complete with cush drive, spacers and axles, just didnt have a rear rotor. A bit narrow at 2.15 front and 2.5 rear but still work OK with 2nd slicks and I can use them as spares on my FZR bucket and TZR post classic bike

You could try some Heidenau Tyres on your 18 inch rims, Get hold of Alex, Ridelife or Racey Rider on here for availablity and pricing. I am getting some for my sons KR150 street stock bike, they come in race compound and suit the narrow rims. You MUST use Dot Legal road tyres for SS150 class, No such rules for your bucket ;-)

[F5 Dave]

Yeah I run with 2.15 front on the 50 just fine. So 2.15F 3"R at a squeeze, 2.5 & 3.5 ideal to use 125 GP slicks. You can run a front on the rear & indeed I did for years on the 50, but bigger is better when the power & weight gets up a bit.

Thats a good deal. Head to a wreckers for a disc, tends to be the cheaper option, if you can find one whats not fucked.

Thats NSR143 trademe name, 2KR FZR rims are the same as 1KT TZR. 2.15 front and 2.5 rear.

With the CB125T bucket just run with what tyres you have got (if there not really shagged) Maybe change to 17's later or sell the bike and buy something else. Just get out there and do it is the main thing.

Roys Hill is this weekend people :scooter:

I have a spare rear rotor for the wheels I got, I have got a FZR/TF bucket thats just about ready and 3 TZR's in variuos states. One just about road legal (for the Welly 2Stroke Ride), one getting a RZ350 engine and one to be a bucket or spares for others

Thanks Jase.
Just having problems getting hold of them at the moment.
New race compound tyres are being made at the German factory this month, so they'll be "Still warm off the molds" when they do arrive.

What tyre size are you looking for on the 18" CT125t rims?

Alex.

that sounds like a good compromise; I'll need to have a quick test ride round the block first to see how the current sizes feel. Interestingly the front is a 2.75x18 and the rear a 90/90 18... yet they are the same brand and tread pattern.....

How much are these likely to cost?

[RideLife]

The Heidenau K45 RSW race compound 2.75 - 18" $193
K65 RSW 3.00-18" (90/90. - a front tyre, but fine for the rear), $220

Prices are that of the last shipment, but next lot should be in that ballpark.

I don't know what they are like compared to slicks, but I have used one at manfield and pukekohe (just this weekend gone) on the rear of the 57 Domy and they are comparable in grip to AM20 Avons. Can't remember the tire type but its 110/90-18 from memory. Sticks like shit to a blanket.
