Any idea what is the waiting period?
Once you have done the full payment, its 7 working days here in Chennai.

Re: Triumph Speed 400 Review

So Shumi today said in the Hero Mavrick 440 MotorInc First episode that people are saying the Speed 400 is slowly becoming boring for some of its long-term owners. BHPians on this thread who have ridden it all this time, is it getting boring?

Re: Triumph Speed 400 Review

Based on the current February 2024 mapping, it is for me. It has become slower revving with the recent update. I max out (engine feel/comfort zone) at 80kmph now mostly. Bike can maintain 120 plus but we need to wring the accelerator for this now (again). They have dulled down the throttle response. Wasn't the case with Jan 2024 ECU map; was fun to ride. Used to frequently hit 110-120 on the highway on that map just cause it felt quicker to reach those speeds.

Re: Triumph Speed 400 Review

Just to check out the accuracy of speedo console after watching a YouTube video, i took a test ride and tried to check the rough gps speed with Google maps. Was surprised to see that the bike had almost 15kmph of speedo error till 100 and that only grew to approx 20 as I pushed it to 120 on speedo max. Just to verify, I tried the same with other yamaha and ktm bikes and the same was within 8-10kmph error.

I have a feeling in a bid to make the bike super friendly and tractable in the city, they could only manage 250-300cc levels of top end(although it reaches there faster courtesy it's punchier mid). And the speedo has been calibrated to show optimistic speeds for psychological factors. This also substantiates the opinion of the motorinc folks wherein they say that the bike can cruise comfortably only upto 105 110. This would translate to 120-125 speedo readout for us regular folks.

Anyone with better gps device can test and share the result?

Not one bit! I'm enjoying riding every minute of it.

For reference, I got my bike in the first week of September, which means I probably have one of the first few lots of bikes. I have done close to 4000kms and I can still grin ear to ear when I wring the throttle and zoom past the rest of the world. What an engine, what brakes, and oh my god the suspension. Still stands out at every traffic signal. There is nothing boring about this bike.

Have I gotten more used to the power? Yes, of course. But all it takes is a quick ride on my old apache 160 or any average car and I miss the hell out of my speed 400. Getting used to the performance and getting bored of a bike is a huge difference. Even people with 1000cc superbikes get used to their bikes but doesnt mean they are bored and need an "upgrade" to the esteemed journo's beloved Duke 390.

Shumi just doesnt seem to be getting over this bike. He brings it up every single time there is something even around the price or performance segment and misses no chance to take pot-shots for no reason, similar to what he does with the Honda CB350 series. He needs to get over it, to be honest.

To get certified, the manufacturer has to maintain an accuracy within 5-10% as far as I know. Anything beyond that will probably get flagged before the bike is allowed to be sold. I am not defending this but even the EU has this regulation.

The polling rate (frequency of signal being received) of the GPS module needs to be very high for accurate speed calculation. You need dedicated GPS hardware to achieve high levels of accuracy (like the vbox used for verifying records).

Any mobile phone based app just isnt capable of giving very accurate instantaneous speed readings. That is why you will even notice a slight delay in the speed reflecting in these apps. Some apps seem to use some sort of interpolation or extrapolation to make it look instantaneous.

A mobile phone usually polls GPS at 1Hz (once per second) while the vbox polls at up to 100 Hz (up to 100 times a second). You can imagine how much of a difference that can make when you are at high speeds (120 kmph = 33 m/s). Sure, you can still get a decent idea of average speed using the mobile's GPS.

The funniest one I have seen is people using those speed trap cameras with LED displays, on some expressways and saying that that is more accurate than the speedo inside the car . Ok buddy.

Additional info: Chart from EU regulations

Interesting read. Thank you. Would be nice if we get a vbox comparo for all the 250-400cc bikes with regards to the actual speed timings. Strange then that ktms have such an accurate speedo readings.
