Hero HF Deluxe: BS4 vs BS6 Differences

Is the update limited to just cleaner emissions?

The launch of the Hero HF Deluxe BS6 was a bit of a surprise, mostly because we didn’t expect 100cc bikes to make the transition to BS6. But considering that this 97.2cc sloper motor contributes nearly 80 per cent of Hero’s sales in India, perhaps the brand was compelled to do so. Now that we have India’s first 100cc BS6-compliant motorcycle with us, let’s see how it’s changed from its predecessor:

What’s Changed?

The engine continues to displace 97.2cc but it is now fed by a fuel injection system rather than a carburettor. As a result of this, power output has dropped from 8.36PS to 8.02PS. And while peak torque has remained the same at 8.05Nm, it is now delivered 1000rpm higher than before. But what this bike’s target audience will greatly appreciate is the claimed 9 per cent increase in fuel efficiency over its BS4 counterpart. 

Interestingly, despite losing engine output, Hero claims 6 per cent faster acceleration on the BS6 version. An additional catalytic converter has been added on the exhaust downtube to clean up tailpipe emissions. The HF Deluxe BS6 is also the second fuel-injected Hero bike to feature the brand’s i3S idle stop-start system, after the Splendor iSmart BS6.

The BS6 version of the HF Deluxe is identical in terms of design to its BS4 predecessor, and the only difference comes in the form of new graphics and colour options on the updated motorcycle.

What Hasn’t Changed?

The rest of the motorcycle remains unchanged, which means that the updated BS6 motor continues to be housed in a double cradle chassis suspended on a conventional telescopic fork and dual preload-adjustable shock absorbers. 130mm drum brakes at both ends bring the bike to a stop, and CBS is standard. The HF Deluxe BS6 rolls on 18-inch alloy wheels wrapped in 2.75 x 18 rubber at both ends, just like before. All dimensions remain unchanged as well.

Pricing & Variants

The number of variants has been cut down to just two from the previous six. There are no kick-start variants on offer anymore, and the only two trim levels you can have the bike in are Self-Start Alloy-wheel and Self-Start Alloy-wheel i3S. As you’ve probably guessed, the only difference is the presence of the i3S idle stop-start system.

These two variants are around Rs 8,500 more expensive than their BS4 counterparts, priced at Rs 55,925 and Rs 57,250 respectively. This is quite reasonable considering the addition of fuel-injection and an extra catalytic converter.
