Traditionally styled bikes are following the same path as adventure bikes. Each new retro is bigger, more powerful and glistens with added tech – and is ever-more expensive. Enter the new Benelli Imperiale 400, bobbing into shot with its 21bhp single, basic chassis and £3699 on-the-road price.

First seen at the EICMA show back in 2017, the Imperiale has finally arrived and is a ‘reinterpretation’ of the lightweight Leoncino models that Benelli made in the 1950s (we’ll gloss over the fact they already have a 500cc twin in their range called the Leoncino).

It uses a brand-new 374cc air-cooled, twin-spark single designed specifically for the model, and that proudly wears a ‘made in China’ sticker on the side.

Benelli have officially been ‘Benelli QJ’ since 2005 when they were bought by Chinese automotive giants Qianjiang – there are 19 people working on engineering, design and prototyping at the firm’s historic Pesaro base in Italy, but all models are manufactured at the QJ factory. Bikes for Europe go through quality control in Italy before being distributed.

In a world obsessed with authenticity you may question the validity of a Chinese-built bike using supposed Italian heritage. But you could say something similar about Triumph. And, actually, if you want an authentic retro experience Benelli’s Imperiale 400 provides just that.

It’s a very period riding position, with arms out to fairly close bars, and hips and knees bent at 90˚ to the slightly forward footpegs.

If you’re reading this on the loo you’re probably in a similar sort of stance. The chassis is easy enough to swing about and behaves itself at low speed; there’s lots of old-school engagement and feel through the basic suspension, and the slim tyres bring agility.

The Benelli doesn’t have the most balanced ride out in the country, though. The twin rear shocks are a little too firm and allow a paltry 55mm of wheel travel while the forks have a slight tendency to go boing, and the Benelli can be vague and wobbly in 60mph corners on a B-road. Enfield’s Bullet has superior steering and composure, and so gives greater confidence.

The engine is as steady as you’d expect a small capacity 21bhp single to be. With determination it’ll just about indicate 80mph, though obviously this is a bike intended for breezy Sunday morning trundles, and it’s happiest thrumming around up to about 60mph.

It revs more freely than Royal Enfield’s benchmark Bullet – the redline is 6000rpm but it’ll push on until almost 7000 – and is considerably smoother as well. The five-speed gearbox has quite a bit of lever travel, but the action is light.

Sure, some elements hint at the 400’s modest price. There are a few sloppy frame welds, the wheels don’t sit perfectly centrally in the mudguards viewed side-on, and the brackets for the cable clutch are made from what a metallurgist would call ‘cheese’. But overall the finish and presentation are spot-on for the price.

Small-capacity, simple retros like the Imperiale are thin on the ground these days with models getting bigger, more complicated and more expensive - just look at the £13,000
Triumph’s latest Thruxton RS but there are alternatives out there.

The main problem for the Benelli is that a Royal Enfield Bullet is just £500 more. It’s proven, has better handling, its traditional chugging single is more characterful and authentic, and Enfields have cast-iron residuals, too. It feels like the bike the Benelli is trying to be.

And there are more options to consider between these two price points, too. Spend an extra £1500 and you can get the Royal Enfield Interceptor 650, the bike that toppled the BMW GS off the top of the sales chart in 2020.


2 out of 5 (2/5)

Given the Imperiale is just a whisker over three-and-a-half grand there are some pleasing touches. The stainless-steel peashooter exhaust is perfectly finished and the clocks wear pleasing surrounds.

The engine finish appears high quality, mudguards are steel rather than flappy plastic, the brake lever has a span adjuster, and there’s nothing amiss with the switchgear. I like that the indicators have the warm period-style glow of bulbs too, rather than the sharp on-off you get with LEDS.

And I like the framework on either side of the rear wheel, though have no idea of its purpose.

A decent cheap little single. It has its problems but does put a smile on your face

Comfy enough riding position Brakes on mine... no complaints Can feel stiff on some bends but overall I like it

Some switchgear feel cheap, but by far the worst problem is corrosion. Within 500 miles not in the winter neither the swingarm had started to show flaking on the paint, whilst not a disaster it's not good on a new bike. I think if the paint was thicker this would not be as serious. At 1000 miles the galvanised plates on the chain adjustment system have serious rust issues, again its not been run in the winter apart from when it went back to the manufacturer end of 22 for cutting out issues. It had been tested in the wet after all the snow. It was covered in all sorts of shit and crap not even washed off. Basically the paint on the frame is woefully thin and some cheap electrical materials are used.

Value vs rivals 5 out of 5

20 mile round trip to work 5/7 days less than £8.00 Cheap filters and I'm guessing brake pads too. Tyres won't be an issue either in the cost department

Equipment 3 out of 5

Runs out of steam quickly, but, it makes you smile. Exhaust note is absolutely spot on Easy to do an hour and a half before needing a break, that said I am 6'5"

Buying experience: Bought new from a dealer, great experience. Had cutting out issues and both the dealer and MotoGB were great. Apart from MotoGB sending it back covered in mud and salt from the road test

Running cost is the Imperiale's best feature. Corrosion is it's worst

Ride quality & brakes 4 out of 5

Although I think the build quality is abismal on my little Imperiale, the damn thing always puts a smile on my face when I ride it! The clutch is heavy, the brakes aren't great and I wouldn't even attempt to ride the bike two up but on my own going down a nice back road or country lane the bikes great fun.

Engine 5 out of 5

I've given the engine's performance a top rating due to it being fine if you take into account that it has only 21hp and don't expect to much of it. When you get the bike wound up its actually not to bad, it's a great little machine to through around.

Reliability & build quality 2 out of 5

I've covered 8000 miles on my Imperiale and almost every part of the bike has suffered with corrosion issues, wheel rims, front fork stanchions, rear socks, all the shiny 'chromed' parts l, the bikes frame, in fact you name it and It's corroded. Oh and a spring snapped on an internal part of the gear linkage!

The bike looks really good, the worst features are the poor visibility from the mirrors, the bike is worth the money, just for the thrill factor.

Ride quality & brakes 3 out of 5

In general the bike is just a good all rounder, it brings a smile to your face, it just gives you such a relaxing feeling. I haven't taken a pillion yet, but I have ridden for over 2 hours without any problems.

Engine 4 out of 5

Single cylinder, it does the job, it won't beat any land speed records, but the bike is designed for that, its designed for a nice and relaxing ride out into the countryside and forget all your troubles.

Reliability & build quality 4 out of 5

I have had no problems with corrosion yet,the only problem that I have encountered is faulty hazard light switch, which was down to poor quality of wiring, and bad soldering joints.

Value vs rivals 4 out of 5

I live in europe so the service cost is about 89.00 exchange

Equipment 4 out of 5

The exhaust note is just perfect, you don't need to go and get an after market exhaust.I have brought some bar end mirrors because the original mirrors are useless, especially if you have broad shoulders.The tires are ok, not the best.

Buying experience: I brought the bike in europe, where they dealer is pretty poor, there is no such thing as customer service or professionalism. Forget your warranty its worth nothing, hence that's why I fixed my own problem.

Overall very pleased with the bike. Handles well. Performance is adequate in my opinion. So far no problems and the finish is holding up well. As others have mentioned a front mudflap is a worthwhile addition. No drilling required as the holes and fixings are already there. How thoughtful

Some have complained about the harsh rear end. This can actually be adjusted. I find it fine as it is

No issues in this area looks stunning when clean. And notbing has failed. Prepared to a very high standard by the dealer including copper grease to the bolts. Wish more would do the same

4 out of 5 What a Bullet should be ...

I love the bike, I've had it since the end of January. Having had a Bullet 350 before, and, I also have an Interceptor, I can safely say, I'd pick the Imperiale over the Bullet any day, and it compliments my Interceptor perfectly. Onto which, comparing the Imperiale, or Bullet for that matter, to one of the Royal Enfield twins, is not an altogether valid comparison, they are very different bikes. As for the suspension, yes, i agree with the article, however, it's not really an issue, and it's something you quickly come to terms with. Performance wise, now it's run in it will comfortable reach 70 two up, so, whilst not having blistering acceleration it is basically any type of road, including motorway, capable, but, it is more at home on A, B and unnamed roads, this is where it feels alive !!. I have really only found 2 negatives, first off, if intending to ride in inclement weather, almost not optional over here, then you need to fit a mudflap to the front mudguard. Also, the spokes, appear to oxidise a little quicker than I'd like, no sign of rust, but they are losing their 'shine'. Aside from that, I can't fault the bike, it looks and feels like you'd expect a retro single to be.It will be interesting to see the difference between this and the new 530cc version due out later this year

All good, just the rear suspension the only minor niggle

Engine 5 out of 5

Thuds along merrily, feels like plenty of torque

Just misses the mark but it easy to forgive its failings as it's a retro bargain.

Ride quality & brakes 3 out of 5

Rear suspension very poor, oversprung and under damped although it improves a little with the weight of a pillion, brakes once beaded in are ok but with only 22hp and good engine braking the brakes dont get used as much.

Engine 4 out of 5

Could do with more power to make A road progress a little less frightening.

Reliability & build quality 5 out of 5

So far nothing has failed and no warranty claims!

Value vs rivals 5 out of 5

80 miles plus to the gallon so its frugal.

Equipment 4 out of 5

The speedometer may be illegal a reading at 5000 rpm is 70mph but the actual speed is 61 mph, naughty! Headlight beam is very good and the dash vista for such a competitively priced mmachine is nice. But the rear shocks in a word dreadful you'll feel every pot hole and bump on the B roads and unclassified country roads which is where the Benelli will generally be best suited.

Buying experience: Purchased at full listed price from Bennett's whose care and service has been excellent.

This bike for me is perfect. It is my first 'big' bike since passing my test last year. It is not super powerful but at the same time you can push it to its limit without scaring yourself silly. The sit up and beg riding position is very comfortable and the bike is very well balanced and rides like a dream. It is also very easy to manoeuvre and put on the main stand without assistance (I'm just a feeble woman after all!)

Ride quality & brakes 5 out of 5

I could easily ride for a couple of hours without a break which is enough on any bike. The brakes are very good and the bike handles really well in the hands of a novice like me

Engine 5 out of 5

If you are expecting superbike standard you will be disappointed but for someone like me who wants a safe and enjoyable ride it is perfect

Reliability & build quality 5 out of 5

It is very nicely built and cleans and polishes up really well (I have a black one and it looks stunning). I ride it almost every day commuting to work and it has not had any issues

Value vs rivals 5 out of 5

I service the vehicle myself so save on labour costs. As far as fuel goes it probably costs me about £10 per week compared to £30 per week using the car

Equipment 5 out of 5

My favourite features are the gear indicator and the analog speedo. Also the fact that the lights are on all the time you are riding

Buying experience: I bought this from a dealer in Nottingham. They didn't have one in but they ordered one from the main warehouse and it came in 4 days.
