Grom riders in my area were out riding with a rider on a new 2022 Grom.

They found it slower compared to one of the group rider's stock 2014 model, they exchanged bikes and found the same results.

I watched an online video of a 2022 Grom highway test, seemed the engine torque was weak in 5th gear and the speed was easily affected slight incline, tucked or not tucked, drafting or not drafting cars, etc.

I was looking renew my stock 2014 daily driver with a 2022 but unsure now.

No 2022 model flames intended, just trying to understand what others have experienced to make a decision, new 2021 or 2022?

Could engine break-in be a factor?

When I bought my 2018 it had less than 600km on it and it wasn't notably more powerful than my 2022 that I bought with 0.6km on it.

Then again it does seem like some groms are not built equal to others. The intake tract on my 2018 was horrible, especially where the insulator met the head.. Maybe the attention to detail has diminished even more now that these bikes are in such high demand?

I found this to be completely the opposite from my first hand experience. My stock 22 grom was hitting 68-69 on flat ground with no draft, only slightly tucking down. Then drafting on highway at 76-77. 2014 can’t do that

That's reassuring......my 2014 only hits 62'ish with no wind.

Any other 2022 owner comments?

I have a 14 and a 22. The 22 eats the 14's lunch from my observations. When the 22 slows on an incline in 5th it's just a matter of downshifting to 4th and wind her up.

You can accelerate in 5th but I wouldn't use it to overtake as it would be a slow ordeal, it's like an overdive gear that's missing on the 14.

That makes perfect sense and what I was expecting with the 5 gear.

Thanks

Crazy if you are actually getting those speeds out of a stock 22 grom. Mine will only hit 60 on flat ground in 5th gear. Itll get up to 62 redlining in 4th though lol.

On the 22 I feel like the 5th gear addition was to give better fuel eco or something as well as leave room for extra rpms from mods.

Don't really know shit about motorcycle companies decision though

Recap so far 2022 vs 2014 Grom:

1. 22 vs 14 - about the same
2. 22 - 66-68 mph
2. "22 eats the 14's lunch"
3. 22 - 60 mph in 5th gear, 62 in 4th redlined

Any other 2022 owners?

Could be a gearing issue:

How many rpms is 60 mph on the 14?
How many rpms is 60 mph on the 22?

What is the 4th gear ratio on the 14 gearbox?
What is the 5th gear ratio on the 22 gearbox?

...and what are the front and rear sprockets on each?

14 - 62, mine is redlined, flat, no wind
22 - ?

14 ratios - 1st 2.5, 2nd 1.55, 3rd 1.15, and 4th .923
22 ratios - 1st 2.846, 2nd 1.777, 3rd 1.315, 4th 1.034 and 5th 0.843

14 - 15 / 34 tooth
22 - 15 / 38 tooth

Found these values on searching internet, hope they are correct.

You guys must be a younger generation than me, I'm 52 and can remember the days that top speed even if just for a moment or two beats all. I guess to me its the torque to get to speed and keep it there thats most important, hitting 70 on a slight downhill doesnt do it for me cuz that next uphill grade well u know what happens......
Have now ridden two generations 20,22 the 22 gets my vote due to gearing (5-speed) and comfort the 22 seems just to have a bit more punch and i just fit way better on the 22.

Agree with everything you said, I am 64.

First things I changed on my 2014 were for comfort, adding a Corbin seat and heightened the handlebars.

In my initial post I questioned the torque from watching a video and ask for other's experiences....... "seemed the engine torque was weak in 5th gear and the speed was easily affected slight incline, tucked or not tucked, drafting or not drafting cars, etc."

Torque is the true measure of power and the ability to maintain speed.

Open to all providing their experiences..........

Thanks for the useful information. :)

14's cog gearing is 2.26 and 4th gear ratio is .923 for an overall gearing of 2.08

22's cog gearing is 2.53 and 5th gear ratio is .843 for an overall gearing of 2.13

This is extremely close with the 22's gearing being just slightly lower than the 14.

So just for fun, which first gear is lower?

14's cog gearing is 2.26 and first gear is 2.5 for 1st gear ratio of 5.65

22's cog gearing is 2.53 and first gear is 2.846 for a 1st gear ratio of 7.2

So 22's have a WAY lower first gear! o_O
That will make the 22's engine feel WAY stronger.

So given your results, are you saying the 22 will pull slightly harder in 5th gear than the 14 in 4th?

Yes... but only slightly because the 22's top gear is just slightly lower than the 14's, so the 22's engine rpms will be a little higher at the same speed.

I'm not really sure if such a slight gearing difference would even be noticeable unless the 22's cam was different from the 14's cam. that would make FAR more difference.

Thanks for the explanation........

Looking at the other 22 lower gear ratios, if would appear the 22 should be somewhat quicker than the 14, maybe not much faster.

Would you agree?

that would make sense. More gears= theoretically easier to stay in the power. Maybe no higher top speed but it’ll get there much quicker and easier, even with having to shift and extra time.

I must have the slowest 2022 Grom, about 57-58 on flat ground flat out unless I duck, and then I might see 63-64 tops, never seen 65 on flat ground.
