125cc vs 100cc: Which Engine Actually Makes Sense for Gujarat Highways?
By Bhavik Munjapara, Founder – ABTADKA.com & TechBhavik.com

I still remember 2020 like it was yesterday. I had just started ABTADKA.com from my small room in Sihor, Bhavnagar. My first “company bike” was a 100cc I bought second-hand for ₹42,000. Hard-earned money. I thought, “Bas, city me chal jayegi. Kitna deti hai, wahi important hai.”

Then came my first client meeting in Ahmedabad. 170 km one way. Summer, 43°C on the dash. NH-8 with trucks flying past. That day I understood what real Gujarat highways demand from a bike.

In my 4 years running ABTADKA and testing 30+ bikes across Bhavnagar, Rajkot, and Ahmedabad, I’ve seen too many friends buy the wrong engine size and regret it within 6 months. So let’s settle this once and for all – 100cc vs 125cc for our highways, our heat, and our pockets.

1. Why I’m Writing This After 4 Years of ABTADKA

When I started ABTADKA.com in 2020, my goal was simple: no showroom dalal-giri, only real user advice. I’ve done Bhavnagar to Surat at 2 AM, Rajkot to Dwarka in peak monsoon, and daily Sihor to Bhavnagar commutes on roads that eat suspension for breakfast.

I’ve noticed a pattern. Students and first-job professionals walk into showrooms asking for “best mileage bike.” Salesman sells them a 100cc. Six months later they call me: “Bhavikbhai, highway pe truck overtake nahi hota. Engine chillane lagta hai.”

This guide is for them. For you. Because we Indians don’t buy bikes every 2 years. We buy once and expect it to run till our kid goes to college.

2. What “Highway” Really Means in Gujarat

Highway here isn’t Delhi-Mumbai Expressway. It’s NH-8, NE-1, and SH-25 where you get:

• 45°C heat from April to June. Your engine oil becomes water.
• Salt-air humidity near Bhavnagar-Pipavav belt that rusts chains in 3 months.
• Sudden crosswinds near Ahmedabad-Vadodara stretch that push light bikes.
• Trucks doing 80 km/h in the left lane, and you need 90 km/h power to overtake safely.

On my testing in Sihor, I noticed my old 100cc would sit at 70 km/h with the throttle pinned. Vibrations like a mixer grinder. 125cc? Same road, 85 km/h at 70% throttle, engine still calm. That 15 km/h difference is life and death when a trailer is behind you.

3. 100cc Bikes: Where They Win and Where They Cry

Where 100cc is King:

1. City mileage: Sihor to Bhavnagar daily 35 km? A Splendor gives me 68 km/l. That’s ₹2.1 per km at today’s petrol price.
2. Low maintenance: Clutch plates ₹350, oil 900 ml only. My 2020 bike’s service bill never crossed ₹1,100.
3. Light weight: 110 kg. Easy for college kids and women to handle in Ahmedabad traffic.

Where 100cc Cries on Gujarat Highways:

1. No reserve power: At 60 km/h, you have nothing left to overtake. I’ve seen too many close calls near Bagodara.
2. Engine stress: Running at 95% RPM for 2 hours straight in 44°C heat? Engine life drops fast. My friend’s 100cc needed a bore job at 38,000 km.
3. Crosswind stability: Light weight + skinny tyres = scary on the Ahmedabad-Rajkot wind corridor.

4. 125cc Bikes: The Sweet Spot or Overkill?

After testing the Shine, Glamour, Raider, and Pulsar 125 across Gujarat, here’s my honest take:

Why 125cc feels made for our highways:

1. That extra 25cc is not just 25%. It’s 30-40% more torque. Means you cruise at 80 km/h without the engine screaming. On my Bhavnagar to Ahmedabad runs, the 125cc stays at 5,500 RPM vs 7,500 RPM on a 100cc. Lower RPM = lower heat = longer life.
2. Better brakes & tyres: Most 125cc bikes now give disc brakes and 100/90 tyres. In monsoon, the Tarapur-Vataman stretch becomes slippery. That extra grip matters.
3. Still “Kitna Deti Hai” friendly: My test Shine 125 gave 58 km/l on highway runs. Only 10 km/l less than a 100cc, but you reach 20 mins earlier and with less fatigue.

When 125cc is overkill:
If your running is only Sihor village to Bhavnagar city, 25 km max, no highway ever, save the ₹15,000 and buy a 100cc. That money is better spent on a good helmet.

5. Will This Bike’s Engine Survive the Ahmedabad Heat?

This is the #1 question I get in DM. Short answer: 125cc survives better. Here’s why.

In my 4 years at ABTADKA, I’ve opened engines of both. At 45°C ambient temp, a 100cc running at 80 km/h hits oil temps of 130°C+. Mineral oil breaks down. A 125cc doing the same speed is at 110°C because it’s less stressed.

Bhavik’s Heat Survival Tips:

1. Oil grade: Don’t use 10W30 on highways in May. I switch to 10W40 semi-synthetic. ₹200 extra, but engine stays 8°C cooler. Tested with IR gun.
2. Spark plug: NGK G-Power instead of stock. Better heat range for long runs. ₹180 investment.
3. Mid-day breaks: Every 80 km, stop under a tree for 10 mins near a Galla. Let it cool. Your back and the engine both need it.

6. The “Kitna Deti Hai” Reality: Mileage on NH-48 vs City

Showroom will tell you “70 km/l mileage sir.” Reality for Gujarat highways:

Riding Condition	100cc Actual Mileage	125cc Actual Mileage	₹ Cost per 100 km @ ₹103/l
Sihor City Stop-Go	65-68 km/l	55-58 km/l	100cc: ₹151, 125cc: ₹178
NH-8 Cruise 70 km/h	58-62 km/l	52-55 km/l	100cc: ₹172, 125cc: ₹193
Full Throttle 85+ km/h	45-48 km/l	48-50 km/l	100cc: ₹221, 125cc: ₹210

Notice that? At high speeds, 125cc is more efficient because the 100cc is maxed out. For anyone doing 40+ km highway daily, the ₹21 per 100 km difference is nothing compared to engine life saved.

7. Bhavik’s Longevity Guide: Keeping Your Bike New for 7+ Years

We Indians hate changing bikes. My 2020 bike still looks new. Here’s my monthly “Sihor-style” routine that costs under ₹300/month:

1. Chain Cleaning – Kerosene vs Lube Debate: Every 500 km. I use kerosene + toothbrush to clean, then Motul C2 lube. Coastal salt air near Bhavnagar kills chains. Lube alone without cleaning = grinding paste. My chain set lasted 28,000 km.
2. Paint Protection from Gujarat Sun: Park under shade. If not possible, use a ₹250 cover. Every 3 months, I do Collinite 845 wax. UV in Saurashtra is brutal. My friend’s red bike became pink in 2 years. Mine didn’t.
3. Engine Health: Air filter clean every 2,000 km. Dust from village roads chokes it. Clogged filter = 5 km/l mileage drop. I tap it out myself behind my house.
4. Battery: Remove and clean terminals with Vaseline before monsoon. Humidity + salt = green fungus on battery.

I’ve kept this routine since 2020. Result: My bike’s resale quote is ₹8,000 higher than others of same year. Small habits, big money saved.

8. Resale Value After 5 Years: ASCII Chart Comparison

I called 3 used-bike dealers in Bhavnagar and Ahmedabad. Here’s average resale for 2019 models in 2024:

Resale Value % of On-Road Price After 5 Years
100cc Bikes  ############################ 55% 
125cc Bikes  ################################## 68%

# = 2% value. Data from Bhavnagar, Rajkot, Ahmedabad dealers

Why? Highway users prefer buying used 125cc. Demand is higher. A 100cc is seen as “city only” so dealers negotiate harder. On a ₹90,000 bike, that 13% gap = ₹11,700 back in your pocket.

9. Data Table: 4 Popular Bikes Compared for Gujarat Riders

Bike Model	On-Road Ahmedabad ₹	Highway Mileage	Service Cost/Year ₹	0-80 km/h Time	Best For
Hero Splendor+ 100cc	₹82,500	60 km/l	₹3,200	14.1 sec	Pure city, <20 km/day
Honda Shine 125cc	₹96,800	54 km/l	₹4,100	10.8 sec	Daily 40km+ highway
TVS Raider 125cc	₹1,03,400	52 km/l	₹4,600	9.6 sec	Young riders, style+power
Bajaj CT 125X	₹89,200	56 km/l	₹3,800	11.5 sec	Village roads + highway mix

Prices June 2026, Ahmedabad RTO. Mileage tested by me Bhavnagar-Ahmedabad route.

10. Bhavik’s Verdict: Who Should Buy What

Buy a 100cc if:
You’re a student in Bhavnagar city. College-ghar-tution. Max 25 km/day. Highway once a month. Budget is tight. You want cheapest to run and maintain. Splendor or HF Deluxe. Don’t overthink.

Buy a 125cc if:
You do Ahmedabad-Sanand, Rajkot-Morbi, or any 30+ km highway run 4+ days a week. You value safety while overtaking trucks. You plan to keep the bike 5+ years. Spend the extra ₹15,000. It pays back in resale, engine life, and your peace of mind. My pick: Shine 125 for reliability, Raider 125 if you’re under 25 and want power.

Who should save money: If you’re thinking “I’ll upgrade to a car in 1 year,” don’t buy 125cc. Take a used 100cc for ₹45,000, use it, sell it next year.

11. Why Trust ABTADKA?

I’m not a Delhi influencer who rides bikes for 1 day. I’ve been riding Gujarat roads since 2016 and writing at ABTADKA.com since 2020. Every bike here I’ve ridden 300+ km myself – not showroom test rides. I pay for my petrol. I face the same 45°C heat you do.

ABTADKA’s promise: If I won’t recommend a bike to my younger cousin in Sihor, I won’t recommend it to you. No paid reviews, ever. That’s why 1.2 lakh Gujaratis read us monthly.
