Hi guys,

How is the general feedback on Conti Go! when compared to MRF Zapper?
I'm not referring to any specific size. Just a general opinion.
And wasn't Modi Tyres taken over by Continental earlier this year?

Thread approved and merged

hey the pics are attached.

the tyre is called 'Dunlop Tuff Grip'. its tubeless. It cost me 2650/-. so i think its a VFM, coz its cheaper than MRF also. its size is 120/80/17, same as stock. but it looks taller than stock. it looks like 120/90/17.

has got decent grip in wet. grip in dry is also good. slightly better than stock, both wet & dry. i had a proper ride in both dry & wet today, & never felt out of control, even in heavy rains.

but the noticeable improvement is in the ride quality. it feels much more comfortable than stock while tackling the pot holes. all in all a very decent tyre at a very decent price.

Modding tyres for better grip in the rain.

Firstly, thank you, moderator, for merging my thread.

I had had to change the tyres on my Pulsar Classic 150 and opted for a Michelin M45 in front and a TVS Jumbo in the rear.

Very soon, I found the rear tyre skidding at the slightest provocation - a moderately wet patch of road taken at a modest 40 kmph and a modest lean angle was enough. Everything else on the bike was ok esp the rear swingarm bearing etc.

I traced the problem to the lack of a central groove on the tyre. As we know, treads on a tyre act as pumps to flush out water and keep the surfaces in contact with the road dry. The new tyre lacked this groove and so the central part of the tyre was not able to establish a good, dry contact with the road.

I decided to cut a central groove in the rear tyre - had read of this sloution for the then exotic HH CBZ way back in 2001 or so. The foto is the tyre with the groove cut and adjacent to it is a foto of a stock tyre.

Lacking a Dremel drill, I had to to it the manual way with a paper cutter. The result was not pretty but was effective in stopping the skids.

Now, my new CBR 250 too is showing those signs and I plan to do the same job but with a Dremel this time.

Feedback is welcome.

Hi danny,

I have a CBR 250 with Conti Go at both ends and a P150 Classic with formerly Zappers at both end.

I would very strongly recommend the Zapper - the Conti skids on turns in the wet.So much so that I am going to mod it as I did for my TVS Jumbo, the post.

With Zappers, you will be safe in the dry as well as the wet.

i have a small query over here.i have fitted m45 4x18 on rear in my karizma.but the tyre is quiet big to fit.si it is not 100% in line with the bike and is in small angle with the bike line. will it affect anyway to the bike? like chain,sprocket,or berings? also the rear sprocket is coupled on rear axle or is it independent from the axle??

Geez, I was seriously considering a Continental tyre for my FZ. The stock Revz does not have a good wet grip. Recently, a lady on a Scooty crossed my path. The road was wet after a rain. I hit the brakes, initially the rear, and whoosh....the wheel locked and I skid for a few metres. I was able to bring the bike to complete stop after applying the front disc brake.
Even when I hit a sudden brake on dry road, the rear fish tails. I have had countless close shaves. I am a careful rider. But every thing is not in our hands.

The front Zapper FX is exceptionally good. Has a very good wet and dry grip.
Because of fish tailing I usually use a combination of front and rear brakes.

I went to a local tyre shop for a nitrogen fill. I just asked the guy if there is an alternative for Revz. He said: Yes we have Conti, price Rs 3200. Not a bad price. Revz also cost almost the same.

Got ContiGO in my front 110/70. Now regret on doing so to save 500 over Pirelli SD 100/80

can any one suggest me... i am planning to change the rare tyres OF R15 Ver 2.0... no particular reason just dont like the broad tyres

1. planning for MRF vyde 120-80-17 instead of 130-70-17
2. is the mrf vyde is a radial tyre...
3. what is the weight of mry vyde 120-80-17 & 130-70-17
4. how are vyde tyres are they good .. i mean any review

plz soon bcoz i am going to get mine on 14 sept

Rear Tyre grip issue

I have a Yamaha Gladiator SS 125 and a couple of months before i got tyres changed both front and rear on the bike. Front is Michelin M45(2.85-18) and Rear is Michelin Sirac Street(3.00-18). Initially I used to get good grip from the tyres in both dry and wet conditions. Even under hard braking the bike used to be stable.
Rode a good 1500 kms on the new tyres and was very happy with the stability and grip i was getting.
Things started to change after i serviced the bike last month and since then the bike's stability under braking has become seriously questionable. When applying just the rear brakes hard at slow speeds(10-20 Km/h), the rear wheel is getting locked and the bike skids slightly. Imagine how it will be at speeds of 40-50 km/h. The rear of the bike skids nicely when braked hard at 50 ish speeds and sometimes the engine cuts off itself. Not sure why this is happening. All this is hapenning after i got my bike serviced from my local mechanic after the tyre change.

Tyre gurus here please help me out as to what is causing this instablity and lack of grip.

Thanks,
emzee.

One sincere suggestion-don't do it.
Reasons:
1. The R15 rear tyre will be light, sticky&offer lots of feedback.
2. MRF Vyde may last longer, but will be heavier. Rubber is not as soft compound also.
2. The ride height will change in case of Vyde (96mm. as opposed to 91mm. in case of R15 V2.0 tyre)
3. R15's rear tyre is a radial tyre-do read about the benefits of having radial tyres as opposed to normal ones.
All in all, its like paying money and spoiling something good that you are getting.
If you still wanna do it at the cost of losing handling, accelaration&mileage, go ahead, your choice. Rims will still support it.

@emzee: I think the mechanic has overtightened the rear brake. Try loosening it up a bit. I have the same tyre combo on my Fiero F2&it only gets better with time. Though I did feel the same things you have mentioned now in the early stages, but it has mostly settled down now. Another point was I had downsized from a 100/90 tyre.
If the issue still persists, get the wheel bearings checked. I found mine to be gone.

bro thanks for the info... the only reason i dont like wide tyres.. bcoz it look wide and require more energy to drag.. after this clear info from you,.. i will not even think of changing

thanks for the info... oce i got my bike sure i will disturb you one more time.. dont mind bro
cheers

No problem bro, feel free to ask me whatever you want.
Please read about the advantages of radial tyres-one of the main advantages is that, they are lighter&more agile inspite of being wide!
Yamaha spent a lot of time with MRF designing the tyres for FZ&R15. This time also it has the same tread pattern&compound, but with a radial tyre.
In case of R15 V1, MRF made 6 prototypes before Yamaha approved the 7th one.
Drag, rolling resistance, everything is optimized.
Only downside is due to stickier rubber you get lower life of approx. 15K kms. compared to ~25-30K kms. of regular compound tyres, but the performance, dry&wet grip more than make up for it.
Hope I was of some help.

Thanks for your suggesstions Sarvajit. Will try loosening the brakes a bit and see how it goes.

emzee
