@ Rosh : my bike topped out at 110 on the speedo stock with indian tvs clutch plate so i am figuring a true top speed of 100 kmph at least ... however i believe that the shogun is all about devastating roll ons than true top end... the quick in city accleration is enough to plaster a smile the width of africa inside my helmet and see the other bikers go mad in the next traffic light where the shogun waits for them ha ha...

It has both top end n acceleration. . .best acceleration is seen after 30 kmph. .i was able clock about 115 (with hefty pillion rider)

Agree back in 1997 my friend had a stock shogun used to hit 110 + consistently on the speedo with me as pillion... the power kicks in around 4500 - 5000 rpm climbs till 7000 rpm... onwards on my current shogun (with the Catcon) the power band of non catcon models could be different...

But catcon performs n roars (especially when its ripped)

Very true

140Kmph on a Shogun!!!!!!!! Are you serious!!!

What i am curious to know is, if it was wobbling at 110Kmph, then how were you riding this bike at 140Kmph??? How did you manage??? Was Superman at your service???

And you say you race with ZMAs & RDs....... WOW man........ You are sure going to race with Rossi someday.

Its been 7 long years after this post. Is your shogun still doing 140Kmph or crossed 300Kmph already???? I am sure you must be racing your 110cc machine with R1 & Busa already.

+ 100000 E+100000


185 Kmph on an RX ?????? I just fell of my seat reading this post. Making an RD do such speeds is a daunting task, and we are talking RX here. Please post some realistic figures, this is pure BS.

a pure race setup rx can do 185 buddy.....but that would mean that the engine would have to be rebuilt after every 2-3 quarter mile drags........our friend here is probably just exaggerating.....

I am still learning, long way to go. Can you please post some pics of any speed runs where an Indian RX has done 185Kmph. Its always better to validate your claims, than speculating.

can any one enlighten me please.

The mentioned figures like 140kmph and 185 kmph are speedo, gps gun reading ? where bike actually running at those top speed??( will the machine and transmission support those high revs)

OR

quater mile drags where crossing a distance of 402.336600 meters at some T seconds and multiplied to bring these total figures?

eg: 185 kmph = 185/60 min = 3.083333 kms per minute

3.083333/60 seconds = 0.0513888 kms =51.3888 meters/second

so 402.336600/51.3888 = 7.829 seconds for crossing a quarter mile drags on RX

Nice mathematical calculation there Vijay. This is the kind of technical response i like. Awesome.

7.829 secs on an RX !!!!!!!

@ Revhard, even a stock Yamaha R1 (1000cc) will not do that kind of timing!!!!

In India the RX135 does around 13.xxx Sec (Only a handful of tuner have achieved this) for 402.3366 which brings the avg speed in Km/h to,

402.3366 Mts = 0.4023366 Kms.................... (1)
13.2 Secs = 13.2/3600 = 0.003666 Hrs...........(2)

Avg Speed = (1) / (2) = 109.728 Kmph.

Now at this avg speed, the exit speeds is around 150-152Kmph (at the end of 402 mts). The top speed is ofcourse the Speed Gun values actually measured at races. So in a nutshell an Indian RX135 fully done to drag specs with a good rider is able to do a 13.xx secs for 402 mts with a top whack of 150Kmph.

For the record, go through all the major motor sport clubs which hosts the drag racing & there check the timing for 130-165cc 2-stroke category. No 2-stroke in this category has ever done 12.xxx secs, that league is reserved for RD350.

Now just trying the relativity theory (a.k.a scaling), if the top speed was 185Kmph then the quarter mile timing will be,

150 Kmph ----------> 13.2 Secs
185 Kmph ----------> ? = 135.33 Kmph

135.33 Kmph = 37.5916 m/sec

So for 402.3366 mts it will take approx., 10.7 Secs which is not possible under any circumstances for an RX135.

What Vijay has done is taken the Top speed & not the average speed and thats the reason his timings are further reduced. In any drag racing event we take the average speed of the machine as it is 0Kmph to xxx Kmph at the end of 402 mts, unlike in circuit racing (lap timings) where the bike or car is already in motion (this is how it is in F1 qualifying).

Hope i have clarified in the best possible manner with all the proofs & calculations.

Once again i request to all newbies, this is xbhp 2-strokes forum, not some crap FB or orkut discussion thread to claim speeds like these!!!! Kindly refrain from posting such un-realistic figures.

Thanks for understanding.

Note: I have been with 2-strokes for 12 long years now & my tuner has been in Drag Racing since 1988. He has raced a TVS50, Hero Puch 65cc, RX100, RX135 & now building a drag spec RD350. So we know very well what we claim.

I seriously doubt that buddy...! AFAIK, those mentioned by you might either be the Speedo calculated or ur missing something. The realistic speed on even those Big-Bore kit's would ideally be 150-160 to the max at the exits which when averaged out from start would be somewhere around 110+ and not definitely around the 185 mark & how many drag Rx'es are fully faired?? To my knowledge all they carry is just a thin double bubble visor mounted in the fork brackets..

@ revhard, Would help a bit to understand ur claim if it was true as you said.

Good one...! & 7.829 is like Even the best timing in a fuly Race blown RD is something like 12.XXX. Proof for the same....Deccan Quarter Mile results for the year 2009, not many changes this year so posting this...



Very Sensible & informative for easy understanding.

Karthik thanks for clarifiying.

what i still needs to know is, wheather any RX even after exiting quarter mile if still it continue on straigt stretch what would be max possible top speed it can reach on gun? 140-185? possible?

Thanks ram & thanks for posting those actual drag race results.

Vijay, drag based RX/RD/any bike are meant to cover 400mts in minimal time. They are not top speed driven.

But if you were actually interested in testing the top speed alone & not worried about timing, then with some sproketing changes an RX135 can reach speeds upto 160-162Kmph, maybe within 1000mts or so. The capability is there to cross 100mph bracket, but most tuners lock it for timing reasons. There is no point in streching the bike anymore as now the reliabilty comes into picture, the crank will blow & there will be big hole in the piston if the bike keeps on going. This is the reason such modified machines are highly un-suitable for street use.

For street modified avataar, i would say 130-135Kmph is a safe figure, beyond which again it forays into drag setup & making it pathetic for street use (unless somebody wants to move the bike with power band opened always!!!!!!).


And yes these are all Speed Gun results only.

S.Rajesh, there is our rider. Tuner is Kanna of Vinod Motors. Check the timings for RX100 & RX135.

P.S: Can't believe the 350 of Mr.Abdullah Ali Amoodi took 47.xx secs to complete 400mts. Not sure what he was doing on track!!!

i'm sorry guys i did not mean to say that any drag setup rx can do 185 in a quarter mile
i mean to say that given enough open road and an extremely radical engine setup it is possible.
obviously not in the quarter mile though

and for why no tuners opt for such radical setups is that the engine would give up after 2-3 runs. and rebuilding a drag spec engine every 2-3 runs is surely not possible
