If your bike sleeps on the street, buy the Kryptonite New York Fahgettaboudit 1415 and leave it locked to your parking spot. If you carry your lock with you every day, buy the Abus Granit Detecto 8077 alarm disc lock.
I have watched riders buy the toughest lock on paper, then leave it at home because it weighs as much as a bowling ball. A lock only works when it is on the bike. Kryptonite builds the heaviest chain in this fight. Abus builds the smartest portable locks.
The right choice has less to do with the spec sheet than with where your bike spends the night, which is the one question most theft-prevention guides never ask.
What Does Each Brand Sell to Riders?
The two brands come at motorcycles from opposite directions. Kryptonite is a bicycle-lock company that motorcyclists adopted because its top chain is simply enormous.
The New York Fahgettaboudit 1415 pairs 14mm six-sided 3t hardened manganese steel links, five feet of them, with the New York Disc Lock and its 15mm shackle. It weighs 15.25 pounds, rates 10 out of 10 on Kryptonite’s own scale, and retailers list it as Sold Secure Motorcycle Gold and Thatcham CAT3 approved.
Kryptonite’s product page puts numbers on its anti-theft protection offer: up to $5,000 for bicycles, $2,000 for powersport, once you register the lock. That is real money back if a thief defeats the lock on a motorcycle.
Abus works the other way: a German security company with a dedicated motorcycle line. Its two flagships here are the Granit Detecto XPlus 8077, a 13.5mm-bolt alarm disc lock with a 100dB siren and 3D motion sensing that weighs under two pounds and sells for about $180, and the Granit CityChain X-Plus 1060, a 10mm hexagonal chain in lengths up to 170cm that weighs about 6.5 pounds, carries Sold Secure Gold and the Dutch ART 4045 motorcycle rating, and sits at Abus’s top security level of 15.
Replacement keys come through Abus’s code card system: you can order them, but there is no theft-payout program and no free keys, which is the one area where Kryptonite clearly leads. Specs above come from Kryptonite’s 1415 page and Abus’s CityChain page.
How Do They Compare, Dimension by Dimension?
| Dimension | Kryptonite Fahgettaboudit 1415 | Abus Detecto 8077 / CityChain 1060 |
|---|---|---|
| Security rating | 10/10 house scale; Sold Secure Motorcycle Gold; Thatcham CAT3 | Abus level 15 (top); Sold Secure Gold; ART 4045 motorcycle |
| Lock types | One massive chain-plus-disc-lock combo; no alarm model | Alarm disc lock plus mid-weight chain; full motorcycle line |
| Weight and portability | 15.25 lbs; a lock you leave at your spot | Under 2 lbs (disc) or about 6.5 lbs (chain); built to carry |
| Keys, warranty, theft cover | Key Safe program ships 2 free replacement keys; limited lifetime warranty; $2,000 powersport theft payout (registered) | Code card key ordering (paid); no theft-payout program |
| Grinder resistance | Flagship U-lock: 5 min 35 sec per cut in independent FUB testing | Flagship U-lock: 4 min 13 sec per cut in the same test series |
On the grinder numbers: the French cycling federation’s lock committee cut both brands’ flagship U-locks with a battery angle grinder, and each one forced several minutes of work and multiple discs before giving up.
Those were bicycle U-locks, not these exact products, but the takeaway holds for the motorcycle line: at this tier, both brands buy you time and noise, and time plus noise is what sends a thief looking for an easier bike. The full test write-up is worth a read if you want the gory details.
Which Lock Wins for a Street-Parked City Bike?
The Kryptonite, and it is not close. Fourteen-millimeter links against ten. Five feet of chain that reaches lamp posts, railings, and parking meters the shorter Abus chain cannot, plus Sold Secure Motorcycle Gold certification.
The move street riders actually use: buy the chain once, wrap it around your regular pole, and leave it there. Nobody steals a 15-pound chain off a pole, and you never carry it.
Two honest caveats from owners. The nylon sleeve over the chain can scuff paint, so thread the chain through the wheel and the pole, never across the tank.
And no chain on earth stops four people and a van, so a street-parked bike wants a tracker as backup. Read whether an AirTag can protect your motorcycle before you decide the chain alone is enough.
If you are loyal to Abus, the honest street setup is the pair: the Detecto 8077 alarm on the disc plus the 170cm CityChain locked to something fixed. It costs more than the Kryptonite combo and the chain is lighter duty, but the alarm adds a layer the Kryptonite cannot.
What About a Shared Apartment Garage?
A shared garage has foot traffic, tailgaters, and neighbors who prop the door. You want the bike chained to a ground anchor or a pillar, and either brand’s chain does that job.
The tiebreaker here is Kryptonite’s registered theft coverage: $2,000 back on a powersport claim is a real consolation if someone defeats the lock in a garage you do not control. I have seen owners describe exactly this setup: a Fahgettaboudit chained to a ground anchor in an apartment lot, holding for months.
Abus has one practical edge in tight shared space: the CityChain coils down small enough to stash under a seat or in a tail bag, so it is not draped across a parking spot your neighbor also uses. If your garage assigns one narrow slot and frowns on clutter, that matters.
Which Lock Fits a Suburban Home Garage?
The garage door is your security here; the lock is the second layer, and the alarm is what makes a thief leave. The Abus Detecto 8077 wins this one.
A 100dB siren in a quiet cul-de-sac brings neighbors to their windows, and at under two pounds and about $180 it is the cheapest real deterrent in this article. Throw a cover over the bike and a thief now has to make noise twice: once lifting the cover, once fighting the alarm.
The Kryptonite is overkill for this parking spot. Fifteen pounds of chain buys you nothing extra behind a locked garage door, and you will resent hauling it from the garage wall to the bike every single morning.
What Should a Commuter or Tourer Carry Every Day?
Weight decides, and Abus wins by a mile. The Detecto 8077 rides in a jacket pocket. The CityChain 1060 coils under most seats. The Fahgettaboudit at 15.25 pounds stays home, and a lock sitting at home protects nothing.
I have seen this failure mode more than any other: the rider with the toughest lock in the world and a bike parked outside the coffee shop with nothing on it.
Match the lock to the stop. Short stops, gas and coffee, the alarm disc lock alone is fine. Longer stops, the work parking lot or a hotel overnight on tour, add the chain and lock to something fixed.
If you are still torn between the two lock types, our disc lock vs chain lock breakdown walks through the trade in detail, and the alarm disc lock roundup covers cheaper alternatives to the Abus.
Who Should Not Buy the Kryptonite?
Do not buy the Fahgettaboudit if you need to carry your lock every day. Fifteen and a quarter pounds does not fit a commuting routine, and every day you leave it home is a day you paid $250 for a paperweight.
Do not buy it if your paint is fresh or custom. One owner warned the nylon sleeve runs scratchy against expensive paint, so route it through wheels and frames, never across the tank.
Do not buy it for the alarm, because there is not one, and do not buy it for the theft coverage unless you will actually register the lock. The $2,000 powersport payout only exists if you file the registration; unregistered, it is just a heavy chain.
Who Should Not Buy the Abus?
Do not buy the Detecto 8077 as your only lock for a bike that sleeps on the street overnight. A disc lock cannot anchor the bike to anything, and a 13.5mm bolt plus a siren will not stop a thief with time, tools, and no audience. Street overnight needs a chain to something fixed.
Do not buy Abus expecting theft-payout coverage. Unlike Kryptonite, Abus runs no compensation program if the lock is defeated. You are buying metal and engineering, not an insurance policy.
And a small practical one: the Detecto runs on two AAA batteries and its 3D sensor is eager. It will scold you with the full 100dB if you lift the bike off the stand with the lock still on the disc. Use the reminder cable, or your neighbors will learn your schedule.
Best for: the street-parked bike that needs the most metal, the Kryptonite New York Fahgettaboudit 1415. Check the Fahgettaboudit 1415 on Amazon. Fourteen-millimeter links, five feet of reach, Sold Secure Motorcycle Gold, and a registered $2,000 powersport theft payout. Buy it, chain it to your pole, and leave it there.
Best for: the rider who carries the lock every day, the Abus Granit Detecto XPlus 8077. Check the Detecto 8077 on Amazon. Under two pounds, a 100dB alarm with 3D motion sensing, and a 13.5mm bolt through your brake disc. For long stops, pair it with the CityChain X-Plus 1060 on Amazon and lock the pair to something that does not move.
Buy the lock that matches the parking spot. The toughest lock in the world does nothing from your closet shelf.
